I’m trying to get text support for asterisk working, I’m able to get t140 working but when it comes to t140red it does not seem to work. I have followed the instructions provided to me from
videosupport=yes ; needed for proper SDP handling even if only text and voice calls are handled
allow=h263 ; at least one video codec as H.261, H.263 or H.263+ is needed.
Is there something I need to do to either the codebase of the configs to make this work ?
