SIP in higher education

[Chris Kauffman <>]

Oscar,

UCM 6.1(2) does support SIP trunking.  There will be some tuning 
required between CallManager and OpenSER/Kaimilio/OpenSIPS.  We have 
enabled SIP trunking on CallManager 4.1(3) for receipt of SIP calls 
only.  The version of CallManager that we use does not understand SIP 
URIs in it dial plan.

We are working on an upgrade to 6.1(2) that will take place within the 
next 90 days, and there has been some talk of looking at outbound SIP 
routing after the database migration issues are settled.  We could talk 
off-list further if you like.

Thanks very much,

Chris
