I created a device with the same number under applications-> devices and made the user above fixed to the device
Then I attempted to find the location to enable the WebRTC softphone and could not find the location to enable it. Can the view be updated to make that work?
I noticed in the module description, the following information exists:
If you have User and Device Mode enabled any extension you enable the WebRTC Phone a duplicate extension of 99XXXX will be created (where XXXX is the original extension number), when the user then views the web interface of the WebRTC phone they will be connected to device 99XXXX which will receive calls from the original extension
