I have just come across something when pre-staging a Jabber environment. I had two Windows PC machines logged in with the same account details to the internal VCS-C (so would have the exact same Device Address Pattern, although registered from different IPs), then called a Jabber MAC client also registered to the VCS-C which was logged in using different credentials. In one instant the calls worked as expected. In the other the call connected and video and audio from the Mac to the PC worked for around 5 second then froze and stopped. The video and audio from the PC to the MAC continued with no issue.
I then loged out of the client that worked without any problems. I had to restart Jabber on the PC where I saw issue, but then I could successfully make a call to the MAC client without the video/audio dropping. I didn't notice this issue when dialing to a Windows client, although I may need to do more testing with this to confirm.
Is this a limitation what you cannot have multiple devices with the same "Device Address Pattern", and does such registration cause these problems?
Odd problems with multiple Jabber client using a single identity
I think this issue actually relates to the use of ICE/TURN. We had enable ICE as we have found that in some instances, remote users could not connect. However, I can't see a way to specifiy if you want to use ICE in some instance but not others, this then leads to issues between local users.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
