jabber screen share between 2 cucm ?

[Mohammadreza Hadi]

Hi dear friends,

is this possible to have "Jabber Screen Share" between 2 CUCM in two site A & B for example..?
in both site A and B, we have CUCM + CUP (im&presence)

Yes if you have a SIP trunk between the CM system.

Hi dear @Roger Kallberg 

about this scenario, Site A has its own CUCM pub + CUP pub with difference domain from Site B which also has its own CUCM pub + CUP pub,
and this two clusters are completely independent from each other..

is this still possible to have "jabber screen share" between them with just a "sip trunk" between two cucm ?..
or its maybe need to config some sort of "CUP Federation config" between two clusters ?..

It would have been better if you were to include this information in your initial post as it’s a pretty substantial piece of information that changes things quite a bit. I don’t think you can achieve what you asked for without adding additional pieces of equipment to the system landscape to interconnect the two disparate systems. A simple SIP trunk between is for sure not enough and I don’t actually know what would be required.

sorry for less information in first post, you are right..

The only option which could make it possible is "interdomain fedaration" between the IMPs, but I don't know, which features are supported and which not:
