Externall call shows up as "Incoming video call"

[boulianne]

Hey guys,

For some reason, when I receive an external call from the IVR to my extension on the 3CX windows client, it shows "incoming video call" I have the choice to answer with video or audio. Clicking video answers it like a normal audio call. Internal calls straight to my extension are showing regular audio call, so the issue is only with external calls. I tested it with 3 different phones. All getting "incoming video call".
I have already made sure that the "Disallow video calls" option is enabled in my Sip Trunk options.

Any idea how I can fix it ?

Hello @boulianne

This is not an issue with Internal or external calls. This happens because the call comes from a Digital receptionist. Then that happens the SIP flow is different. What happens in that case is that the incoming calls is answered by the Digital receptionist. When a transfer is made the Invite does not contain an SDP (no codecs). The codecs are negotiated when the call is established. Since the client is not aware if the incoming call is audio or video as there are no codecs it brings up both options. Once you press an option the client will send a 200 OK containing the codecs it uses and the PBX will reply with an ACK with the codecs from the incoming call. If no video codecs are present a normal audio call will be established. This is the default behaviour of the client and cannot be changed.
