SIP in higher education

Yul,

I did try do it as you suggest, but I confirmed this doesn't work in the
newer firmware versions (P0S3-06-3-00, P003-07-3-00). 
"Proxy*_address" on each line is not actually the sip proxy
server address, it is the domain.  I.e., for domain we use
harvard.edu, you use hawaii.edu, Dennis uses mit.edu, - these are the
domains but not the sip proxy server addresses.

Steve Blair's answer indicates that the DNS SRV (_sip._udp.bigu.edu) is
what the phones use to find the sip proxy server address.

Candace,
 
Proxy server address is settable in three ways:
1) Manually configure it for each of the line, using the 79x0 phone's keypad
 
2) Set the Proxy1_address field in the SIPmac-addr.cnf file (probably in your TFTP server's sip_phone sub-directory) with the server's dotted IP address or FQDN
 
3) Set the Proxy1_address field in the SIPDefault.cnf file (probably in your TFTP server's root directory) with the server's dotted IP address or FQDN

Thanks Venky, Joseph, and others from Avaya.  Although there is no way to change the domain and realm on the Cisco endpoint, I did get it to register after changing the proxy address from the address of the sip proxy to the address of the domain. 

This may seem like a strange question - how is the phone getting the address of the sip proxy in order to register?  Is it from the SRV record in DNS?

Venky,

 

The registration is failing because the proxys domain and realm is harvard.edu, and the endpoint is registering into the mysipserver.harvard.edudomain.  Notice that in the WWW-Authenticate header of the 401 response from the proxy the realmand domainvalues are both set to harvard.edu.  This tells me that the proxy is configured with harvard.eduas domain and realm.  The REGISTER request from the endpoint specifies a mysipserver.harvard.eduas 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.edudomain and realm and the registration should succeed.

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?
