Hi - Thanks for the coding tip, asterisk neophyte over here!
Your suggested change makes sense to me, but has no effect.
exten => _X.,3,NoOp()
same => n,Set(PJSIP_MEDIA_OFFER(audio)=!all,ulaw)
same => n,Set(PJSIP_MEDIA_OFFER(video)=!all)
same => n,Answer()
same => n,Set(PJSIP_SEND_SESSION_REFRESH()=update) ;send invite with variable
This connects to the trunk with a black video screen.
The only configuration that successfully removes the video is:
exten => _X.,3,NoOp()
same => n,Answer()
same => n,Set(PJSIP_MEDIA_OFFER(audio)=!all,ulaw)
same => n,Set(PJSIP_MEDIA_OFFER(video)=!all)
same => n,Set(PJSIP_SEND_SESSION_REFRESH()=update) ;send invite with variable
but the video screen flashes briefly, very annoying!
