Venky,

 

The registration is failing because the proxy’s domain and realm is “harvard.edu”, and the endpoint is registering into the “mysipserver.harvard.edu” domain.  Notice that in the WWW-Authenticate header of the 401 response from the proxy the “realm” and “domain” values are both set to “harvard.edu”.  This tells me that the proxy is configured with “harvard.edu” as domain and realm.  The REGISTER request from the endpoint specifies a “mysipserver.harvard.edu” as the domain.  The mismatch in domains is causing the registration to fail.

 

Make sure that the endpoint is configured with the same domain and realm as the proxy.  Also, make sure that the CCS user and the phone are configured with the same password.  However, this particular registration would fail because of domain mismatch.  So, reconfigure the endpoint with “harvard.edu” domain and realm and the registration should succeed.

 

Joseph

Bill, Joseph:
I came across this in the SIP.edu mailing list. Is the configuration that they're talking about supported? If so - any idea what the problem could be?

Hi,

I'm getting errors trying to register a Cisco 7960, firmware P0S3-06-3-00 

with an Avaya CCS, version 2.1.0.0-35   There's a continuing auth 

problem.  The exchange of messages is listed below.  Does anyone see the 

problem here?
