Standard phone keypad; press # key to send call; press * key to for IVR functions MAKING PHONE CALLS Handset, Headset and Speakerphone The GXP1100/1105 allows you to make phone calls via handset, headset or speakerphone. During the active calls the user can switch between the handset, headset and the speakerphone by pressing the corresponding keys on the phone. Dual Lines with SIP Account GXP1100/1105 can support up to two lines virtually mapped to a SIP account. The user can switch lines by pressing the FLASH button. Completing Calls There are FOUR ways to complete a call:

1. DIAL: To make a phone call. Take Handset off hook or press SPEAKER button or press HEADSET button The line will have a dial tone Enter the phone number Press # or HANDSET button to send 2. REDIAL: To redial the last dialed phone number. Take Handset off-hook Grandstream Networks, Inc. GXP1100/1105 User Manual Page 7 of 28 Firmware version: 1.1 Last Updated: 06/2011 or press the SPEAKER button Press the REDIAL soft-key NOTE: Dial-tone and dialed number display occurs after the handset is off-hook, or handset button is pressed, or speaker button is pressed. After dialing the number, the phone waits 4 seconds (by default; No key Entry Timeout) before sending and initiating the call. Press # button to override the 4 second delay. Making Calls using IP Addresses Direct IP Call allows two phones to talk to each other in an ad-hoc fashion without a SIP proxy. VoIP calls can be made between two phones if:

Both phones have public IP addresses, or Both phones are on a same LAN/VPN using private or public IP addresses, or Both phones can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ) For example: If the target IP address is 192.168.1.60 and the port is 5062 (e.g. 192.168.1.60:5062), input the following: 192*168*1*60#5062. The * key represents the dot .; the # key represents colon :. Press OK to dial out. The GXP1100/1105 also supports Quick IP Call mode. This enables the phone to make direct IP-calls, using only the last few digits (last octet) of the target phones IP-number. This is possible only if both phones are in under the same LAN/VPN. This simulates a PBX function using the CMSA/CD without a SIP server. Controlled static IP usage is recommended. To enable Quick IP calls, the phone has to be setup first. This is done through the web-setup function. In the Advanced Settings page, set the "Use Quick IP-call mode to Yes. When #xxx is dialed, where x is 0-9 and xxx <=255, a direct IP call to aaa.bbb.ccc.XXX is completed. aaa.bbb.ccc is from the local IP address regardless of subnet mask. The numbers #xx or #x are also valid. The leading 0 is not required (but OK). For example:

192.168.0.2 calling 192.168.0.3 -- dial #3 followed by #

192.168.0.2 calling 192.168.0.23 -- dial #23 followed by #

192.168.0.2 calling 192.168.0.123 -- dial #123 followed by #

192.168.0.2: dial #3 and #03 and #003 results in the same call -- call 192.168.0.3 NOTE: If you have a SIP Server configured, a Direct IP-IP still works. If you are using STUN, the Direct IP-

IP call will also use STUN. Configure the Use Random Port to No when completing Direct IP calls. ANSWERING PHONE CALLS Receiving Calls 1. 2. Incoming single call: Phone rings with selected ring-tone. The corresponding LINE flashes red. Answer call by taking Handset off hook or pressing SPEAKER or HEADSET or by pressing the corresponding account LINE button. Incoming multiple calls: When another call comes in while having an active call, the phone will produce a Call Waiting tone (stutter tone). Answer the incoming call by pressing FLASH button. The current active call will be put on hold. Grandstream Networks, Inc. GXP1100/1105 User Manual Page 8 of 28 Firmware version: 1.1 Last Updated: 06/2011 Do Not Disturb 1.

Grandstream Networks, Inc. GXP1100/1105 User Manual Page 9 of 28 Firmware version: 1.1 Last Updated: 06/2011

Press HOLD to end the conference call and put all parties on hold

To speak with an individual party, select the corresponding LINE key NOTE: The party that starts the conference call has to remain in the conference for its entire duration, you can put the party on mute but it must remain in the conversation. Also, this is not applicable when the feature Transfer on call hangup is turned on. Voice Messages (Message Waiting Indicator) A blinking red MWI (Message Waiting Indicator) indicates a message is waiting. Dial into the voicemail box to retrieve the message. An IVR will prompt the user through the process of message retrieval. Shared Call Appearance (SCA) The GXP1100/1105 phone supports shared call appearance by Broadsoft standard. This feature allows members of the SCA group to shared SIP lines and provides status monitoring (idle, active, progressing, hold) of the shared line. When there is an incoming call designated for the SCA group, all of the members of the group will be notified of an incoming call and will be able to answer the call from the phone with the SCA extension registered. All the users that belong to the same SCA group will be notified by visual indicator when a user seizes the line and places an outgoing call, and all the users of this group will not be able to seize the line until the line goes back to an idle state or when the call is placed on hold. (With the exception of when multiple call appearances are enabled on the server side). In the middle of the conversation, there are two types of hold: Public Hold and Private Hold. When a member of the group places the call on public hold, the other users of the SCA group will be notified of this by the red-

flashing button and they will be able to resume the call from their phone by pressing the line button. However, if this call is placed on private-hold, no other member of the SCA group will be able to resume that call. To enable shared call appearance, the user would need to register the shared line account on the phone. In addition, they would need to navigate to Settings->Basic Settings on the web UI and set the line to Shared Line. If the user requires more shared call appearances, the user can configure multiple line buttons to be shared line buttons associated with the account. CALL FEATURES The GXP1100/1105 supports traditional and advanced telephony features including caller ID, caller ID w/name, call forward/transfer/park/hold as well as intercom/paging.

Send Anonymous Anonymous Call Rejection Auto Answer 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, anonymous call will be rejected. Default is No. If set to Yes, GXP1100/1105 will automatically switch on speaker to answer the incoming call. Set to Intercom/Paging mode, it will answer the call based on the SIP info header from the server. Allow Auto Answer by Call-Info If the Call-Info header contains answer-after=0, the call be answered automatically

(so called paging mode). Grandstream Networks, Inc. GXP1100/1105 User Manual Page 24 of 28 Firmware version: 1.1 Last Updated: 06/2011 Refer-To Use Target Contact Default is No. If set to Yes, then for Attended Transfer, the Refer-To header uses the transferred targets Contact header information. Transfer on Conference Hangup Defines whether or not the call is transferred to the other party if the initiator of the conference hangs up. Default setting is set to No. Preferred Vocoder GXP1100/1105 supports up to 7 different Vocoder types including G.711(a/) (also known as PCMU/PCMA), G.723.1, G.729A/B, G.726-32, iLBC, G.722 (wide-band). Configure Vocoders in a preference list that is included with the same preference order in SDP message. Enter the first Vocoder in this list by choosing the appropriate option in Choice 1. Similarly, enter the last Vocoder in this list by choosing the appropriate option in Choice 8. SRTP Mode Enable SRTP mode based on selection. Default is No. Symmetric RTP Selects whether or not symmetric RTP is supported. Silence Suppression Voice Frames per TX This controls the silence suppression/VAD feature of the audio codec G.723 and G.729. If set to Yes, when silence is detected, a small quantity of VAD packets

(instead of audio packets) will be sent during the period of no talking. If set to No, this feature is disabled. This field contains the number of voice frames to be transmitted in a single Ethernet packet (be advised the IS limit is based on the maximum size of Ethernet packet is 1500 byte (or 120kbps)). When setting this value, be aware of the requested packet time (ptime, used in SDP message) is a result of configuring this parameter. This parameter is associated with the first codec in the above codec Preference List or the actual used payload type negotiated between the 2 conversation parties at run time. E.g., if the first codec is configured as G.723 and the Voice Frames per TX is set to 2, then the ptime value in the SDP message of an INVITE request will be 60ms because each G.723 voice frame contains 30ms of audio. Similarly, if this field is set to 2 and the first codec is G.729 or G.711 or G.726, then the ptime value in the SDP message of an INVITE request will be 20ms. If the configured voice frames per TX exceeds the maximum allowed value, the IP phone will use and save the maximum allowed value for the corresponding first codec choice. The maximum value for PCM is 10 (x10ms) frames; for G.726, it is 20

(x10ms) frames; for G.723, it is 32 (x30ms) frames; for G.729/G.728, 64 (x10ms) and 64 (x2.5ms) frames respectively. Please be careful when editing these parameters. Adjusting these parameters will also change the dynamic jitter buffer. The GXP1100/1105 has a patent dynamic jitter buffer handling algorithm. The jitter buffer range is 20 ~ 200 ms. We recommend using the default settings provided. We do not recommend adjusting these parameters if you are an average user. Incorrect settings will affect the voice quality. No Key Entry Timeout Default is 4 seconds. Grandstream Networks, Inc. GXP1100/1105 User Manual Page 25 of 28 Firmware version: 1.1 Last Updated: 06/2011 Use # as Dial Key This parameter allows users to configure the # key as the Send (or Dial) key. If set to Yes, the # key will immediately send the call. In this case, this key is essentially equivalent to the (Re)Dial key. If set to No, the # key is included as part of the dial string. G723 Rate Encoding rate for G723 codec. By default, 6.3kbps rate is set. G726-32 Packing Mode Select ITU or IETF for G726-32 packing mode. iLBC Frame Size iLBC packet frame size. Default is 20ms. For Asterisk PBX, 30ms might be required. iLBC Payload Type Payload type for iLBC. Default value is 97. The valid range is between 96 and 127. Special Feature Default is Standard. Choose the selection to meet special requirements from Soft Switch vendors.
