[Freeswitch-users] Using H264 with Verto

[Michael Jerris]

It would not be added just because the module is loaded (it would be removed potentially if its not loaded), its either coming from the other leg, or in codec preferences.

Advice on how to prevent or make selective per SIP profile most welcome.

I ask as I observe that enabling mod_av adds the h264 codec even if it’s not listed in vars.xml. In my particular case I would like to use mod_av but select when to use h.264 by destination as opposed to it being included in every sip sdp, but I have not yet worked out how to do so - by chance have you any tips from your testing ?
