I can not seem to disable and stop Freeswitch from adding the m=video to the SDP:

m=video 17076 RTP/AVP 104 105

Is there a channel variable I can set to disable all Video.

The extra m=video keeps getting added.

I only need audio only. This takes up an extra 3 ports that I do not want to take up.
