I have an office setup which has an asterisk server and 2 grandstream phones connected. I am able to make audio calls between the two phones but whenever i want to switch to video call while the audio call is on, it doesn’t switch.
Anyone experienced this before or have idea how this can be resolved.
Asterisk 13 does not have the new stream support, so I don’t know how well (or even if) it would work. 16 would have a better chance as mentioned. The wiki has lots of information on configuring PJSIP.
