I'm in the process of setting up Expressway E & C at my company. Right now, we're only using using Expressway to make outbound SIP calls to BlueJeans. Here is the call flow:
User dials 62777 > Translation pattern on CUCM forwards to Expressway C SIP trunk > Expressway C performs a transform on 63888 to make an outbound SIP call to meet@sip.bjn.vc > Call from Expressway C is forwarded to Expressway E and the call is connected
My issue is with BFCP content. Right now calls from Jabber and Polycom HDX units work as expected when receiving content: the content is the main source no matter who is speaking. When a Cisco codec (I tried with:TX/CTS/SX/EX/DX) is in the call and content should be received, BlueJeans shows the notification that content is being sent but the codec acts like nothing is coming through (once in a while you'll see content for a few milliseconds and it will disappear). The video window containing the video participants that would normally be sent to the corner while content is displayed, is shown full screen.
If one of these Cisco endpoints sends content, it's sent in the regular video channel, so, as expected, other endpoints don't know they're receiving content. This means when a non-presenter speaks and the active presence switching happens, the content window is sent to the bottom.
Any ideas what could be happening here? I assume I'm just missing a check box somewhere on my CUCM trunk configuration.
(I am using the pre-configured "Standard SIP Profile for Cisco VCS," but I was wondering if I should edit the profile to check, "Early Offer support for voice and video calls (insert MTP if needed)")
Thanks,
Sean
