SIP in higher education

Hello Everybody:


We are from the Autonomous Barcelona University(UAB) and recently we 
installed a new VoIP PBX UCCM 6.1(2)from cisco over sip protocol. We are 
thinking to integrate SIP.EDU in our university but we don't have any 
experience of people doing that with our configuration.

Watching the SIP.EDU cookbook and comparing, Our Cisco VoIP PBX  haves a 
coupple of MGCP gateways and SIP support  and we think that is possible to 
integrate with a SIP PROXY that supports Directory to query (like SER), doing 
that the CCM's works as a  sip gateway against the SIP PROXY.

Has anyone any experience with this kind of configuration?


Thanks in advance to  everybody!
