SIP in higher education

[Stephen Kingham <>]

Hi Denesh

I have had it working with the CCM 4.0 talking to SER SIP Express Router.

Asterisk is good for services like Voice Mail, IVR, and H.323-SIP 
Gateway (well sort of) but it is not a SIP Server.

To help with fault find may I suggest you use "ngrep" on the unix server 
you have your SIP Services running.  You get to see all the SIP 
messages.  Here is the command line I use:

ngrep -p -q -t -W byline port 5060
