Video Calling via Asterik

Asterik based system are mainly used for Voice Call over IP. With some modification, it can be also use for Video calling.

In the guide I pasted above, they say to add the following to sip.conf:

In Red Hat Based System, you will find sip.com at /etc/asterik/sip.conf

[general]
videosupport=yes ; enable Asterisk video support

[101]
type=friend
username=101
secret=hidden
host=dynamic
context=internal
callerid=Video Phone <101>
disallow=all ; better for custom-tunning codec selection
allow=ulaw
allow=alaw
allow=gsm
allow=h263 ; H.263 is our video codec
allow=h263p ; H.263p is the enhanced video codec
dtmfmode=rfc2833 ; inband is not supported in compressed codecs like gsm, so we better set it to rfc2833
canreinvite=no ; canreinvite must be set to 'no'

However, with TrixBox you actually just add

[general]
videosupport=yes ; enable Asterisk video support

to sip.conf and the rest,

[101]
type=friend
username=101
secret=hidden
host=dynamic
context=internal
callerid=Video Phone <101>
disallow=all ; better for custom-tunning codec selection
allow=ulaw
allow=alaw
allow=gsm
allow=h263 ; H.263 is our video codec
allow=h263p ; H.263p is the enhanced video codec
dtmfmode=rfc2833 ; inband is not supported in compressed codecs like gsm, so we better set it to rfc2833
canreinvite=no ; canreinvite must be set to 'no'
