Start Audio Call And Enable Video Later

Hi,

when some phone inititates an audio call and sends a re-invite with audio and video later, asterisk will send a “200 OK” response. The response contains sdp with audio and video enabled.

But that seems to be all asterisk does. No other action and no re-invite to the second phone.

Is this a bug or is just some feature not available?

I tried with different versions of asterisk and used both chan_sip and pjsip. One of the phones used is linphone (3.6.1-3).

Thanks in advance.

One thought on - Start Audio Call And Enable Video Later

  • I don’t believe it’s supported to start an audio call and then re-invite to add video, I believe Asterisk requires the call to start as a video call.
