Advanced Device/Template Configuration

Note: Use caution when changing P Values, because if not done correctly, the phone may not register.

Advanced configurations for Grandstream phones can be made for each device individually or on a Device Template. Changing these P Values can override the settings that are already present on the device. Find the Advanced button in the first section of the Device Template or individual Device tab of the PBX. 

In Chrome, open the web interface of a given phone using the IP address of the device. Right click and choose inspect on any field to see the P Value and its setting. 

These settings can be put into a Device Template for all of the same model of phone, and then applied to those phones. It can also be added to devices on an individual basis.
