Key entry cannot be deleted but the phone may prompt error once it is detected Call Features DIRECT IP CALLS Direct IP calling allows two parties, that is, a Handset and another VoIP Device, to talk to each other in an ad hoc fashion without a SIP proxy. Elements necessary to complete a Direct IP Call:

1. Both DP715_US, and other VoIP Device, have public IP addresses, or 2. Both DP715_US and other VoIP Device are on the same LAN using private IP addresses, or 3. Both DP715_US and other VoIP Device can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ). DP715 supports two ways to make Direct IP Calling:

Using IVR 1. Pick up the Handset and press then access the voice menu prompt by dial ***

2. Dial 47 to access the direct IP call menu 3. Enter the IP address after the dial tone and voice prompt Direct IP Calling Grandstream Networks, Inc. Firmware 0.0.0.8 DP715-US/DP710-US User Manual Page 23 of 43 Last Updated: 03/2012 Using Star Code 1. Pick up the Handset and press then dial *47 2. Enter the target IP address. Note: NO dial tone will be played between step 1 and 2. Examples of Direct IP Calls:

a) b) If the target IP address is 192.168.0.160, the dialing convention is

*47 or Voice Prompt with option 47, then 192*168*0*160. followed by pressing the # key if it is configured as a send key or wait 4 seconds. In this case, the default destination port 5060 is used if no port is specified. If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be:

*47 or Voice Prompt with option 47, then 192*168*0*160*5062 followed by pressing the # key if it is configured as a send key or wait for 4 seconds. NOTE: When completing direct IP call, the Use Random Port should set to NO. You cannot make direct IP calls between Handsets since they are using same IP. CALL HOLD Place a call on hold by pressing the Recall button on the Handset. Press the Recall button again to release the previously held Caller and resume conversation. CALL WAITING Call waiting tone (3 short beeps) indicates an incoming call, if the call waiting feature is enabled. Toggle between incoming call and current call by pressing the Recall button. First call is placed on hold. Press the Recall button to toggle between two active calls. CALL TRANSFER Blind Transfer Assume that call Caller A and B are in conversation. A wants to Blind Transfer B to C:

1. Caller A presses RECALL on the Handset to hear the dial tone. 2. Caller A dials *87 then dials caller Cs number, and then # (or wait for 4 seconds) 3. Caller A will hear the confirm tone. Then, A can hang up. NOTE: Enable Call Feature must be set to Yes in web configuration page. Caller A can place a call on hold and wait for one of three situations:

a. A quick confirmation tone (similar to call waiting tone) followed by a dial-tone: This indicates the transfer is successful (transferee has received a 200 OK from transfer target). At this point, Caller A can either hang up or make another call. b. A quick busy tone followed by a restored call (on supported platforms only): This means the transferee has received a 4xx response for the INVITE and we will try to recover the call. The busy tone is just to indicate to the transferor that the transfer has failed. c. Continuous busy tone: The phone has timed out. Grandstream Networks, Inc. Firmware 0.0.0.8 DP715-US/DP710-US User Manual Page 24 of 43 Last Updated: 03/2012 Note: continuous busy tone does not indicate the transfer has been successful, nor does it indicate the transfer has failed. It often means there was a failure to receive second NOTIFY check firmware for most recent release. Attended Transfer Assume that Caller A and B are in conversation. Caller A wants to Attend Transfer B to C:

1. Caller A presses RECALL on the Handset for dial tone. 2. Caller A then dials Caller Cs number followed by # (or wait for 4 seconds). 3. If Caller C answers the call, Caller A and Caller C are in conversation. Then A can hang up to complete transfer. If Caller C does not answer the call, Caller A can press flash to resume call with Caller B. 4. NOTE: When Attended Transfer fails and A hangs up, the DP715 will ring back user A to remind A that B is still on the call. A can pick up the phone to resume conversation with B. 3-WAY CONFERENCING The DP715 supports Bellcore style 3-way Conference. Instructions for 3-way conference:

Assume that call party A and B are in conversation. Caller A (DP71X) wants to bring third Caller C into conference:

1. A presses RECALL (on the Handset) to get a dial tone. 2. A dials Cs number then # (or wait for 4 seconds). 3. If C answers the call, then A presses RECALL to bring B, C in the conference. 4. If C does not answer the call, A can press RECALL back to talk to B. 5. If A presses RECALL during conference, C will be dropped out. 6. If A hangs up, the conference will be terminated for all three parties when configuration Transfer on Conference Hang up is set to No. If the configuration is set to Yes, A will transfer B to C so that B and C can continue the conversation.

123 admin Only Status and Basic Settings Browse all pages The password is case sensitive with maximum length of 25 characters. The factory default password for End User and administrator is 123 and admin respectively. Only an administrator can access the ADVANCED SETTING, Handset Settings configuration pages. Please reference the GUI pages using the following link: http://www.grandstream.com/products/dp_series/DP71x/documents/DP71x_gui.zip . NOTE: If you cannot log into the configuration page by using the default password, please check with the VoIP service provider. It is most likely the VoIP service provider has provisioned the device and configured for you therefore the password has already been changed. IMPORTANT SETTINGS The end-user must configure the following settings according to the local environment. NOTE: Most settings on the web configuration pages are set to the default values. NAT Settings If you plan to keep the DECT phone within a private network behind a firewall, we recommend using STUN Server. The following three (3) settings are useful in the STUN Server scenario:

Grandstream Networks, Inc. Firmware 0.0.0.8 DP715-US/DP710-US User Manual Page 27 of 43 Last Updated: 03/2012 1. STUN Server (under Advanced Settings webpage) Enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server on the internet and enter it on this field. If using Public IP, keep this field blank. 2. Use Random Ports (under Advanced Settings webpage) This setting depends on your network settings. Generally if you have multiple IP devices under the same network, it should be set to Yes. If using a Public IP address, set this parameter to No. 3. NAT Traversal (under the Profile web page) Set this to Yes when gateway is behind firewall on a private network. DTMF Methods DTMF Settings are in ProfileX page. DTMF in-audio DTMF via RTP (RFC2833) DTMF via SIP INFO Set priority of DTMF methods according to your preference. This setting should be based on your server DTMF setting.

This parameter specifies how often the DP715 sends a blank UDP packet to the SIP server in order to keep the hole on the NAT open. Default is 20 seconds. Minimum value is 20 seconds. Use STUN to detect network connectivity Use STUN keep-alive to detect WAN side network problems. If keep-alive request does not yield any response for configured number of times, the device will restart the TCP/IP stack. If the STUN server does not respond when the device boots up, the feature is disabled. Default setting is No. Firmware Upgrade and Provisioning Enables DP715 to download firmware or configuration file through either the TFTP, HTTP or HTTPS server. Via TFTP Server Via HTTP / HTTPS Server This is the IP address of the configured TFTP server. If selected and it is non-zero or not blank, the DP715 retrieves the new configuration file or new code image from the specified TFTP server at boot time. After 5 attempts, the system will timeout and will start the boot process using the existing code image in the Flash memory. If a TFTP server is configured and a new code image is retrieved, the new downloaded image is saved into the Flash memory. Note: Please do NOT interrupt the TFTP upgrade process (especially the power supply) as this will damage the device. Depending on the local network, this process can take up to 15 or 20 minutes. The URL for the HTTP/HTTPS server used for firmware upgrade and configuration via HTTP. For example, http://provisioning.mycompany.com:6688/Grandstream/1.0.0.67:6688 is the specific TCP port where the HTTP or HTTPS server is listening; it can be omitted if using default port 80. Note: If Auto Upgrade is set to No, DP715 will only do HTTP/HTTPS download once at boot up. Firmware Server Path IP address or domain name of firmware server. Config Server Path IP address or domain name of configuration server.

Primary RADIUS Server Set the IP or FQDN of the Primary RADIUS Server. Remote Authentication Dial In User Service (RADIUS). DP715 supports RADIUS for authentication, authorization and billing purposes. Primary and secondary RADIUS server configurations are available to provide redundancy to this feature. In case Primary Radius server becomes unusable, RADIUS requests will be automatically sent to the secondary server. When at least one RADUIS server was configured, the device will allow users to make phone calls only after authorization from RADIUS server has been received. CDR

Default is 2. Default is 3. Allows user to download and save a text file containing all the P values of each setting as configured at that point on the unit. (Note: For Security Reasons, all Passwords wont be Downloaded) Upload Firmware Allows the user to upgrade the firmware with a single firmware file by browsing and loading the file from your computer (local directory). Table 10: Profile Settings Profile Active Primary SIP Server Failover SIP Server Prefer Primary SIP Server Outbound Proxy SIP transport NAT Traversal (STUN) DNS Mode Tel URI When set to Yes the Profile is activated. SIP Servers IP address or Domain name provided by VoIP service provider. Failover SIP Servers IP address or Domain name in case primary server does not respond. Default is No. If set to yes, it will register to Primary Server if registration with Failover server expires IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border Controller. Used by DP715 for firewall or NAT penetration in different network environments. If symmetric NAT is detected, STUN will not work and ONLY outbound proxy can correct the problem. User can select UDP or TCP or TLS. Default is UDP. This parameter defines whether or not the DP715 NAT traversal mechanism is activated. If activated (by choosing Yes) and a STUN server is also specified, then the DP715 performs according to the STUN client specification. Using this mode, the embedded STUN client will detect if and what type of firewall/NAT. If the detected NAT is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the DP715 will use its mapped public IP address and port in all of its SIP and SDP messages. If the NAT Traversal field is set to Yes with no specified STUN server, the DP715 will periodically (every 20 seconds or so) send a blank UDP packet (with no payload data) to the SIP server to keep the hole on the NAT open. One from the 3 modes are available for DNS Mode configuration:

-A Record (for resolving IP Address of target according to domain name)

-SRV (DNS SRV resource records indicates how to find services for various protocols)

-NAPTR/SRV (Naming Authority Pointer according to RFC 2915) One mode can be chosen for the client to look up server. The default value is A Record The default setting is Disabled. If the phone has an assigned PSTN Number, this field should be set to User=Phone then a User=Phone parameter will be attached to the From header in the SIP request to indicate the E.164 number. If server supports TEL URI format, then this option needs to be selected. Grandstream Networks, Inc.

Default is No. If set to Yes, user can place outgoing calls even when not registered (if allowed by Internet Telephone Service Provider) but is unable to receive incoming calls. This parameter allows the user to specify the time frequency (in minutes) the DP715 refreshes its registration with the specified registrar. The default interval is 60 minutes (or 1 hour). The maximum interval is 65535 minutes (about 45 days). Retry registration if the process failed. Default is 20 seconds. Defines the local SIP port the DP715 will listen and transmit. Defines the local RTP-RTCP port pair the DP715 will listen and transmit. It is the base RTP port for channel 0. When configured, channel 0 uses this port _value for RTP and the port_value+1 for its RTCP Default is No. This parameter forces the random generation of both the local SIP and RTP ports when set to Yes. This is usually necessary when multiple DP715 are behind the same NAT. Default is No. If set to YES, then for Attended Transfer, the Refer-To header uses the transferred targets Contact header information. Default is No. In which case if the conference originator hangs up the conference will be terminated. When option YES is chosen, originator will transfer other parties to each other so that B and C can choose to either continue the conversation or hang up. Default is No, this will create a Semi-Attendant Transfer. When set to Yes, device can transfer the call upon receiving ring back tone or SIP message 180. Default is No. you can make a Conference by pressing Flash key. If set to Yes, you need to dial *23 + second callee number. Default is No. When option YES is chosen, the Out Bound Proxy will be removed from Route header. Instance ID as defined in IETF SIP Outbound draft. Default is No. If set to yes all incoming SIP messages will be strictly validated according to RFC rules. If message will not pass validation process, call will be rejected. Default is No. Check the incoming SIP User ID in Request URI. If they dont match, the call will be rejected. If this option is enabled, the device will not be able to make direct IP calls. Default is No. Check the incoming SIP messages. If they dont come from the SIP proxy, they will be rejected. If this option is enabled, the device will not be able to make direct IP calls.

If call is not answered within this designated time period, the callwill be forwarded to the next member of a Hunt Group. Linear, Circular, parallel and Shared line. Default is Circular. Linear style will sort the call to the lowest-numbered available line; this is also called serial hunting. Circular style will distribute the calls "round-robin". If a call is assigned to line 1, the next call goes to 2 and the next to 3. The succession throughout each of the lines continues even if one of the previous lines becomes available. When the end of the hunt group is reached, the hunting starts over at the first line. Lines are skipped if they are still busy on a previous call. Default value is 20 seconds. In case this feature activated using * codes (*92 code), the call will be forwarded after this preconfigured amount of time. Default is 4 seconds. Dialing process is completed and outgoing call is initiated if no key entry occurs during this preconfigured interval. Default is No. Use only if proxy supports 484 response. This parameter controls whether the phone will send an early INVITE each time a key is pressed when a user dials a number. If set to Yes, an INVITE is sent using the dial-number collected thus far;

Otherwise, no INVITE is sent until the (Re-)Dial button is pressed or after about 5 seconds have elapsed if the user forgets to press the Re-Dial button. The Yes option should be used ONLY if there is a SIP proxy configured and the proxy server supports 484 Incomplete Address response. Otherwise, the call will likely be rejected by the proxy (with a 404 Not Found error). This feature does NOT work with and should NOT be enabled for direct IP-to-IP calling. Sets the prefix added to each dialed number. Default is Yes. It allows users to configure the # key as the Send (or Dial) key. If set to Yes, # will send the number. In this case, this key is essentially equivalent to the Dial key. If set to No, this # key can be included as part of number. Dial Plan Rules:

1. Accepted Digits: 1,2,3,4,5,6,7,8,9,0 , *, #, A,a,B,b,C,c,D,d 2. Grammar: x - any digit from 0-9;

a) xx+ - at least 2 digit numbers b) xx. - only 2 digit numbers c) ^ - exclude d) e) f) <2=011> - replace digit 2 with 011 when dialing g)

[3-5] - any digit of 3, 4, or 5

Explanation of example rule (reading from left to right):

^1900x. - prevents dialing any number started with 1900

<=1617>[2-9]xxxxxx - allows dialing to local area code (617) numbers by dialing 7 numbers and 1617 area code will be added automatically 1[2-9]xx[2-9]xxxxxx |- allows dialing to any US/Canada Number with 11 digits length 011[2-9]x. - allows international calls starting with 011

[3469]11 - allow dialing special and emergency numbers 311, 411, 611 and 911 Note: In some cases where the user wishes to dial strings such as *123 to activate voice mail or other applications provided by their service provider, the * should be predefined inside the dial plan feature. An example dial plan will be: { *x+ } which allows the user to dial * followed by any length of numbers. Default is No. When set to Yes a SUBSCRIBE for Message Waiting Indication will be sent periodically. If this parameter is set to Yes, the From header in outgoing INVITE message will be set to anonymous, essentially blocking the Caller ID from displaying. Default is No. If set to YES Call Waiting indication information will not be provided to Handset. Default is No. If set to YES Call Waiting caller ID will not be provided to the handset. Default is Disable. Play the reminder ring when this is set to Enable. Default is No. If set to Yes, anonymous call will be rejected. The SIP Session Timer extension enables SIP sessions to be periodically refreshed via a SIP request (UPDATE, or re-INVITE. Once the session interval expires, if there is no refresh via a UPDATE or re-INVITE message, the session is terminated. Session Expiration is the time (in seconds) at which the session is considered timed out, provided no successful session refresh transaction occurs beforehand. The default value is 180 seconds. Defines the minimum session expiration (in seconds). Default is 90 seconds. If set to Yes, the phone will use session timer when it makes outbound calls if remote party supports session timer. If selecting Yes, the phone will use session timer when it receives inbound calls with session timer request. If set to Yes, the phone will use session timer even if the remote party does not support this feature. If set to No, the session timer is enabled only when the remote party supports this feature. To turn off Session Timer, select No for Caller Request Timer, Callee Request Timer, and Force Timer. As a Caller, select UAC to use the phone as the refresher, or UAS to use the Callee or proxy server as the refresher.

Table 11: DP715 Handsets Settings Ring All Handsets Button Clear all handset registrations Button Enable Subscription Mode Button Ring Handset Profile ID Hunting Group This button will allow you to ring all the handset registered with the base station This button is used to de-register all the handset previously registered with the base station This button will allow you to set the DP715 under subscription mode in order to register a new handset. Note: Subscription mode is automatically exited after 120 seconds. Allow you to locate the handset corresponding to the specific account. Select the corresponding Profile ID between Profile 1 and Profile 2. This feature enables the DP715 to register all existing Handsets with the same phone number. Each incoming call will be routed to first available port in Linear or Circular mode. User may configure all ports as members of the same Hunting Group or it may configure different port combinations for more than one Hunting Group. For example:

Handset 1, 3 and 5 are members of the same Hunting Group, the rest of the Handsets may have separate numbers and may be reached independently. Any Handset, member of a Hunting Group that is not registered with a SIP account, will be able to place outbound calls using the SIP credentials of the primary Hunting Group Handset. Grandstream Networks, Inc. Firmware 0.0.0.8 DP715-US/DP710-US User Manual Page 38 of 43 Last Updated: 03/2012 For example: Port 1, 2, and 3 are members of the same Hunting Group. Handset 1 is registered with a SIP account. Handset 2, and 3 are not registered. Handset 2 and 3 will be able to place outbound calls using the SIP account of Handset 1. Select appropriate value for Hunting Group feature. The original SIP account should be set to Active while the group members should be set to the port number of the Active Handset. Example configuration of a Hunting group:

SAVING THE CONFIGURATION CHANGES Click the Update button in the Configuration page to save the changes to the DP715 configuration. The following screen confirms that the changes are saved. Reboot or power cycle the DP715 to make the changes take effect. REBOOTING THE DP715 BASE STATION FROM REMOTE Press the Reboot button at the bottom of the configuration menu to reboot the DP715 Base Station remotely. The web browser will then display a message window to confirm that reboot is underway. Wait 30 seconds to log in again. CONFIGURATION THROUGH A CENTRAL SERVER Grandstream DP715 Base Station can be automatically configured from a central provisioning system. When the base station boots up, it will send TFTP or HTTP/HTTPS request to download configuration file, cfg000b82xxxxxx or cfg00082xxxxxx.xml, where 000b82xxxxxx is the MAC address of the DP715. It will first request cfg000b82xxxxxx then cfg000b82xxxxxx.xml The configuration file can be downloaded via TFTP or HTTP/HTTPS from the central server. A service provider or an enterprise with large deployment of DP715 can easily manage the configuration and service provisioning of individual devices remotely from a central server. Grandstream has a provisioning system called GAPS (Grandstream Automated Provisioning System) that is used to support automated configuration of Grandstream devices. GAPS uses enhanced (NAT friendly) TFTP or HTTP (thus no NAT issues) and other communication protocols to communicate with each individual Grandstream device for firmware upgrade, remote reboot, etc. Grandstream provides GAPS service to VoIP service providers. Use GAPS for either simple redirection or with certain special provisioning settings. At boot-up, Grandstream devices by default point to Grandstream provisioning server GAPS, based on the unique MAC address of each device, GAPS provision the devices Grandstream Networks, Inc. Firmware 0.0.0.8 DP715-US/DP710-US User Manual Page 39 of 43 Last Updated: 03/2012 with redirection settings so that they will be redirected to customers TFTP or HTTP/HTTPS server for further provisioning. Grandstream also provide GAPSLITE software package which contains our NAT friendly TFTP server and a configuration tool to facilitate the task of generating device configuration files. The GAPSLITE configuration tool is now free to end users. The tool and configuration template are available for download from http://www.grandstream.com/support/tools . SOFTWARE UPGRADE Software upgrade can be done via either TFTP or HTTP or HTTPS. The corresponding configuration settings are in the ADVANCED SETTINGS configuration page. FIRMWARE UPGRADE THROUGH TFTP/HTTP/HTTPS To upgrade via TFTP or HTTP/HTTPS, the Firmware Upgrade and Provisioning upgrade via field needs to be set to TFTP HTTP or HTTPS, respectively. Firmware Server Path needs to be set to a valid URL of a TFTP or HTTP server, server name can be in either FQDN or IP address format. Here are examples of some valid URL. e.g. firmware.mycompany.com:6688/Grandstream/1.0.0.18 e.g. 72.172.83.110 NOTES:

Firmware upgrade server in IP address format can be configured via IVR. Please refer to the CONFIGURATION GUIDE section for instructions. If the server is in FQDN format, it must be set via the web configuration interface.

Grandstream recommends end-user use the Grandstream HTTP server. Its address can be found at http://www.grandstream.com/support/firmware . Currently the HTTP firmware server IP address is 72.172.83.110. For large companies, we recommend to maintain their own TFTP/ HTTP/HTTPS server for upgrade and provisioning procedures.

Once a Firmware Server Path is set, user needs to update the settings and reboot the device. If the configured firmware server is found and a new code image is available, the DP715 will attempt to retrieve the new image files by downloading them into the DP715s SRAM. During this stage, the DP715s LEDs will blink until the checking/downloading process is completed. Upon verification of checksum, the new code image will then be saved into the Flash. If TFTP/HTTP/HTTPS fails for any reason (e.g. TFTP/HTTP/HTTPS server is not responding, there are no code image files available for upgrade, or checksum test fails, etc), the DP715 will stop the TFTP/HTTP/HTTPS process and simply boot using the existing code image in the flash.

Firmware upgrade may take as long as 15 to 30 minutes over Internet, or just 5 minutes if it is performed on a LAN. It is recommended to conduct firmware upgrade in a controlled LAN environment if possible. For users who do not have a local firmware upgrade server, Grandstream provides a NAT-friendly TFTP server on the public Internet for firmware upgrade.

Grandstreams latest firmware is available at http://www.grandstream.com/support/firmware . Oversea users are strongly recommended to download the binary files and upgrade firmware locally in a controlled LAN environment. Grandstream Networks, Inc. Firmware 0.0.0.8 DP715-US/DP710-US User Manual Page 40 of 43 Last Updated: 03/2012 Note: Alternatively, the user can upload the firmware single file from his/her computer using a local directory. For more instructions see below. Also the user can download a free TFTP or HTTP server and conduct local firmware upgrade. A free windows version TFTP server is available for download from http://support.solarwinds.net/updates/New-customerFree.cfm. release can be downloaded from http://www.grandstream.com/support/firmware . INSTRUCTIONS FOR UPLOAD FROM LOCAL DIRECTORY:

Note: Always check the status page to see that the program version has changed. INSTRUCTIONS FOR LOCAL FIRMWARE UPGRADE USING TFTP SERVER:

1. Unzip the file and put all of them under the root directory of the TFTP server. 2. Put the PC running the TFTP server and the DP715 device in the same LAN segment. 3. Please go to File -> Configure -> Security to change the TFTP server's default setting from

"Receive Only" to "Transmit Only" for the firmware upgrade. 4. Start the TFTP server, in the phones web configuration page 5. Configure the Firmware Server Path with the IP address of the PC 6. Update the change and reboot the unit End users can also choose to download the free HTTP server from http://httpd.apache.org/ or use Microsoft IIS web server. CONFIGURATION FILE DOWNLOAD Grandstream SIP Device can be configured via Web Interface as well as via Configuration File through TFTP or HTTP/HTTPS. Config Server Path is the TFTP or HTTP/HTTPS server path for configuration file. It needs to be set to a valid URL, either in FQDN or IP address format. The Config Server Path can be same or different from the Firmware Server Path. A configuration parameter is associated with each particular field in the web configuration page. A parameter consists of a Capital letter P and 1 to 3 (Could be extended to 4 in the future) digit numeric numbers. i.e., P2 is associated with Admin Password in the ADVANCED SETTINGS page. For a detailed parameter list, please refer to the corresponding firmware release configuration template. When Grandstream Device boots up or reboots, it will issue request for configuration file named cfgxxxxxxxxxxxx, where xxxxxxxxxxxx is the MAC address of the device, i.e., cfg000b820102ab. The configuration file name should be in lower cases. Grandstream Networks, Inc. Firmware 0.0.0.8 DP715-US/DP710-US User Manual Page 41 of 43 Last Updated: 03/2012 Firmware and Configuration File Prefix and Postfix Firmware Prefix and Postfix allows device to download the firmware name with the matching Prefix and Postfix. This makes it the possible to store ALL of the firmware with different version in one single directory. Similarly, Config File Prefix and Postfix allows device to download the configuration file with the matching Prefix and Postfix. Thus multiple configuration files for the same device can be stored in one directory. In addition, when the field Check New Firmware only when F/W pre/suffix changes is set to Yes, the device will only issue firmware upgrade request if there are changes in the firmware Prefix or Postfix. MANAGING FIRMWARE AND CONFIGURATION FILE DOWNLOAD No Yes, every 10080 minutes(60-5256000). When Automatic Upgrade is set Yes, every the auto check will be done in the minute specified in this field. If set to daily at hour (0-23), Service Provider can use P193 (Auto Check Interval) to have the devices do a daily check at the hour set in this field with either Firmware Server or Config Server. If set to weekly on day (0-6) the auto check will be done in the day specified in this field. This allows the device periodically check if there are any new changes need to be taken on a scheduled time. By defining different intervals in P193 for different devices, Server Provider can spread the Firmware or Configuration File download in minutes to reduce the Firmware or Provisioning Server load at any given time. Automatic Upgrade:
