sip.conf

To be able to send video during a call, codec h263 and video support must be enabled. This is done by adding three lines in the sip.conf file (Location: /etc/asterisk/sip.conf).

Add the following lines in the [general] tab of the file.

videosupport = yes        ; Enable video 
allow = h263             ; H.263 is our video codec 
allow = h263p             ; H.263p is the enhanced video codec

Reload

Reload the sip.conf file by running the following command in the CLI console: reload
