Howto:External UC

The External UC-server logs on innovaphone UC-object with TSIP?

Yes, TSIP is the recommended transport protocol, since message bodies can get very huge.

Any special settings required?

As soon as the External-UC has registered, the PBX itself will send a SUBSCRIBE(presence) for a "resource-list". The destination URI can be configured at the PBX object (type External UC). The PBX then expects to get a NOTIFY(presence) containing the presence information of all users.
