SIP in higher education

["Steven C. Blair" <>]

If you wish to add a SIP proxy either OpenSER/OpenSIPs or SER will work fine. 
I'm not sure what you mean when you say "... supports Directory to query." 
Both proxy servers will maintain a database of contacts based on register 
messages and a database of subscribers provided you compile in MySQL support.

Does Call manager 6 speak SIP to gateways or does it still only speak MGCP?

What about support for alphabetic userid in the R-URI and DNS SRV support? If 
CCM supports these then you may be able to interoperate with SIP.edu without 
adding the proxy.
