[Spce-user] peer to peer calls

[Serge S. Yuriev]

Hello,

Thank you a lot, Jon.

If I understand correctly we need to permanent register out PBX to get 
incoming calls?
And a bit more advanced question:
Our PBX (Cisco Unified Contact Manager to be more specific) clustered 
and at any time given at least 3 nodes could process incoming calls so 
how can we balance between them for redundancy?
