Multiple Lines and Hunting Groups
The DP755 Base Station has the ability to assign 10 lines to each registered DP730/DP722 Handsets (Up to 10 Handsets) to receive/make calls. When a Handset has many lines configured, users can select specific lines for outgoing calls using the Outgoing Default Line feature. For incoming calls, users can choose either to redirect them to a specific Handset or to many using the Hunting Group feature so as to have the same phone number and incoming calls will be distributed in a Linear, Circular, or Parallel manner among the Handsets active in that Hunting Group. The number of hunting groups is limited by the number of SIP accounts registered to the base station (up to 20 accounts). The hunting group feature is mainly used in office, warehouse, and call center environments to distribute incoming calls in the best way depending on the type of hunt group. In order to configure hunting groups for DP730/DP722 Handsets registered to the Base, users need first to register SIP accounts on DP755 Base Station Account Settings and then assign accounts accordingly as lines for DP730/DP722 Account Assignment.

DP755/DP730/DP722 Provisioning
Configuration File Download
Grandstream SIP Devices can be configured via the Web Interface as well as via a Configuration File (binary or XML) through TFTP/FTP/FTPS or HTTP/HTTPS. The Config Server Path is the TFTP/FTP/FTPS or HTTP/HTTPS server path for the configuration file. It needs to be set to a valid URL, either in FQDN or IP address format. The Config Server Path can be the 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 2 to 3 (Could be extended to 4 in the future) digit numeric numbers. i.e., P2 is associated with the "New Password" in the Web GUIMaintenanceWeb/SSH Access pageAdmin Password. For a detailed parameter list, please refer to the corresponding firmware release configuration template.

The downloaded config file now will display the P value in new format, which has the more meaningful name of the parameter being configured. Below is an example of how new P values look like, please note that the old numeric P values will still be working, for example, in a single config file, the user can choose to use P values in the format of P9 or Pnetworks.static.address.ip.octet.1, or mixed-format for different settings, the device will take all of them. We are still improving the downloaded config file by adding the help text and re-ordering the settings to match the web.
New P values format When the DP755 boots up or reboots, it will send a request to download a file named "cfgxxxxxxxxxxxx" followed by a configuration XML file named "cfgxxxxxxxxxxxx.xml", where "xxxxxxxxxxxx" is the MAC address of the phone, i.e., "cfg000b820102ab" and "cfg000b820102ab.xml". If the download of "cfgxxxxxxxxxxxx.xml" file is not successful, the provision program will download a generic cfg.xml file. The configuration file name should be in lower case letters. For more details on XML provisioning, please refer to: https://documentation.grandstream.com/knowledge-base/sip-device-provisioning-guide/
Handsets Provisioning
To configure the Handsets provisioning, please browse the base station Web GUI at Maintenance Provisioning. This is the same page used for base station provisioning. Handsets shares the settings of base station provisioning in the field in the red rectangle, and has its own settings in the blue rectangle. After enabling Handsets Config Upgrade, need to reboot the DP755 to take effect.

Provisioning Feature
Config Upgrade via: Choose the method that the base station uses to request the Handsets ipei config file. Can use TFTP, FTP, FTPS, HTTP, or HTTPS. Config Server Path: Defines the server path for provisioning. Do not prepend the address with "http://" or any other protocol. Handset Config File Prefix: If configured, only the Handsets configuration file with the matching encrypted prefix will be downloaded and flashed into the device. Handset Config File Postfix: If configured, only the Handsets configuration file with the matching encrypted postfix will be downloaded and flashed into the device
When a DP730/DP722 registers to a DP755 for the first time or an already registered Handsets boots up, the DP755 will send a provisioning request for a file on the configured provisioning server, with location "Config_Server_Path/[Prefix][HS IPEI].xml[Postfix]". For example, if Handsets's IPEI number is 02c332b510, the prefix is "ipei_", postfix is null, and the config server path is "fw.grandstream.com/gs", the request URL is "fw.grandstream.com/gs/ipei_02c332b510.xml.
For more detailed information, please refer to Handset Provisioning Guide.
