Architecture for Cisco Unified Presence for SIP Federation Deployments
Figure 55-1 depicts a Cisco Unified Presence/LCS Federation scenario with the ASA as the presence
federation proxy (implemented as a TLS proxy). The two entities with a TLS connection are the
“Routing Proxy” (a dedicated Cisco UP) in Enterprise X and the Microsoft Access Proxy in Enterprise
Y. However, the deployment is not limited to this scenario. Any Cisco UP or Cisco UP cluster could be
deployed on the left side of the ASA; the remote entity could be any server (an LCS, an OCS, or another
Cisco UP).
The following architecture is generic for two servers using SIP (or other ASA inspected protocols) with
a TLS connection.
Entity X: Cisco UP/Routing Proxy in Enterprise X
Entity Y: Microsoft Access Proxy/Edge server for LCS/OCS in Enterprise Y
