The question was not about the device pool or MRG, it was how the call flow looks like.
As you mention the call which generates the issue is from your smartphone, this would be the first thing, does video work when you dial directly in between the TelePresence system and Jabber on the phone?
Depending on the smartphone video might not be supported, keep that in mind.
If video does not work on the direct point to point call it will most likely not work in a
multiparty scenario neither, ....
If video works, continue to read, if not fix that part first :-)
Next part would be when you initiate the multi party call how is that done and where does
the call end up.
You have different scenarios, rendezvous, ad-hock or scheduled.
I assume you are talking about ad-hock meetings.
In any case it would be important to hear how the call is established at the end.
Scenarios I see:
* multiparty call is locally hosted on the SX80, when no multisite license is present an additional call would be added as audio only
* call gets escalated to an audio only MRG, but that would also stop the initial video
* call gets escalated to the MCU but video is missing for the Jabber participant
(additional troubleshooting is needed in between the MCU and Jabber).
