Cisco Unified CallConnector Mobility Service 

Technical Overview 

A single UCC Server can be shared by users on multiple Cisco CME systems. 

 

 

 

There are a number of configuration rules and network requirements for such multi-router systems. 

 

Maximum Number of 
Routers 

It is recommended that no more than 5 ISR/UC500 routers be 
connected to the UCC Server 

Maximum number of 
users per UCC Server 

The maximum number of users per UCC Server is 250 users 

TCP/UDP Control 
Messages 

Network must provide bandwidth and minimum latency for the control 
messages. RADIUS messages are transmitted as UDP messages. 
TCP sessions are used to transport the SCCP/Skinny messages 
between the CME router and the UCC Server 

UDP Media for RTP 
messages 

Calls handled by UCC Mobility Service include the SNR and DISA 
calls. The media for these calls flows from the CME router with the 
PSTN Gateway to the UCC Server. The UCC Server only supports 
G.711 codecs (64 KBPS for each voice direction)
