After a nearly 20 year hiatus from Asterisk when I left a Wall Street trading software company, I find myself building out a system to cover an amateur radio community across multiple states in the Northeast USA. We have SIP audio calls, voicemail, conference rooms and IAX2 trunks all working. I am anticipating a request for video call capability by some of the emergency management offices that we support. Videosupport=yes has been tuned on for all users and the Asterisk core. The H264 codec has been turned on for all users and the RTP ports are 40000-40049. Testing with MicroSIP on my laptop and Linphone on both an Android phone and a Linux laptop can not get a video call going. Where should I be looking to activate video calling? Thanks in advance.

Firstly, I would recommend that you upgrade to a supported version of Asterisk
(assuming that the 16.28 in your subject line tells us the version you are
using). Asterisk Versions - Asterisk Documentation
Secondly, show us the endpoint configuration (ie: the entries in pjsip.conf)
for one of your clients so we can see the exact settings for ourselves (I
assume all three clients are defined pretty much the same).
Finally, show us a SIP trace including SDP for the call setup (both the Invite
and the acknowledgement).
Basically, try to give us enough information about what you are working with
that we could reproduce it for ourselves and see what’s going on.
Antony.
