Provision Principle Autop (Auto-Provisioning), this feature is used to configure or upgrade devices in batch via third party servers. Akuvox products use DHCP/PNP/TFTP/FTP/HTTP/HTTPS network protocols to get URL, and then download firmware and/or its corresponding configuration files from that server. These configuration files and firmware will be used to update firmware and the corresponding parameters on the phone. 80 R20B Admin Guide 5.15.1.1. Config File Automatic deployment has the following applications:

General configuration provisioning: In this scenario, a general configuration file is stored in the server and all devices download the same configuration file to update their parameters. MAC based configuration provisioning: In this scenario, each configuration file is for a specific device with the MAC address that matches the file name. The parameters in this configuration file are for that specific device only. This is normally for the account related parameters. If you have both of these files on the server, IP device will first get the General configuration file first and then get the MAC based configuration file using its MAC address as the ID. 5.15.1.2. AutoP Schedule Akuvox provide different AutoP methods to let the device can do phone provisioning in a fixed time. To setup schedule, you can do as follows:

Parameters Set-up:

Power On: Device will start to do AutoP every time it boots up. Repeatedly: Device will start to do AutoP by following the predefined 81 R20B Admin Guide schedule. Power On + Repeatedly: Combined with Power On mode and Repeatedly mode. Device will start to do AutoP when every time it boots up or by following the schedule. Hourly Repeat: Device will start to do AutoP every hour. 5.15.1.3. Procedure to setup AutoP A complete automatic upgrade process consists of the following:

1. Administrator sets up the NPS and ACS servers with the required information;

URL. update. 2. Device gets the URL of the TFTP/FTP /HTTP/HTTPS server;

3. Device download the configuration file from the configuration server with 4. If configuration file contains the content for updating any configurations or upgrading the firmware, device will get the firmware and do a firmware By default, a profile resync is only attempted when Akuvox products are idle, because the upgrade might trigger a software reboot interrupting a call. 5.15.2. PNP for Autop PNP stands for Plug and Play (Plug and Play). PNP provides a proprietary automatic upgrade, when PNP upgrade mode is enabled, the phone will broadcast a SIP SUBSCRIBE in the network. A SIP server will reply with a SIP NOTIFY with the URL of the firmware and/or configuration file server. 82 R20B Admin Guide Tip:

Akuvox do not provide PNP server. 5.15.2.1. Procedures to setup PNP AutoP To setup PNP AutoP, you can do as follows:

1. Click Upgrade - Basic. 2. Make sure PNP(Under the path Upgrade-Advanced on the web GUI of device) is enabled. 3. Export Autop template from Export Autop Template. Following the steps to get PNP AutoP done(Under Power On mode):

1. Rename the AutoP config template(here we upgrade for mass devices, so make it general configuration provisioning). 2. For general configuration provisioning: r0000000000xx.cfg (There are 12 digits in total, for example: C315 --

r000000000115, R29 --

3. For MAC based configuration provisioning:<MAC_Address of the r000000000029 ) device>.cfg, eg. 0C110504AE5B.cfg. 83 R20B Admin Guide server. 4. Upload firmware to DHCP/TFTP/FTP/HTTP/HTTPS server. 5. Edit AutoP config template. 6. Upload the AutoP config template to DHCP/TFTP/FTP/HTTP/HTTPS 7. Run PNP server and fill in the URL of AutoP config template. 8. Click start to start PNP AutoP. 9. Power on devices, they will start to upgrade after booting up. Note:

Remember to turn off PNP server after AutoP done. 5.15.3. Autop via User-Specified Server Users can manually set a specific server URL for downloading the firmware or configuration file. If autop schedule is set, the phone will do the auto provisioning on the specified time frame as set in the autop schedule. We can also use FTP, HTTP, or HTTPS as the protocol for upgrading the 84 device firmware or configuration. R20B Admin Guide Note:

The format of them are as follows:

TFTP: tftp://192.168.0.19/

FTP: ftp://192.168.0.19/

1. Click Upgrade - Basic. 2. Export Autop template from Export Autop Template. Following the steps to get User-Specified AutoP done:

1. Rename the AutoP config template (here we upgrade for mass devices, so 85 R20B Admin Guide make it general configuration provisioning.);

2. For general configuration provisioning: r0000000000xx.cfg (There are 12 digits in total, for example: C315 --> r000000000115, R29 -->

r000000000029 ) 3. For MAC based configuration provisioning: <MAC_Address of the device>.cfg, eg. 0C110504AE5B.cfg. 4. Upload firmware to DHCP/TFTP/FTP/HTTP/HTTPS server;

5. Edit AutoP config template;

6. Upload the AutoP config template to DHCP/TFTP/FTP/HTTP/HTTPS 7. Enter TFTP URL into the box(under the path Upgrade-Advanced) and 8. You can also power device up to make it work when PNP server is server;
