Candace:
Right. For example. Say your phone config file has an
entry proxy1_address: harvard.edu. The phone boots,
checks it's tftp server for a config file. Downloads the
file and uses _sip._udp.<proxy1_address> as an SRV
service name. It attempts to resolve this into an A record
or CNAME.
In your case this works. If it were to fail then the phone
fails over to a certain DNS "lookup" sequence. I forget
what the sequence is but I think it is SRV, A, CNAME.
It repeats this process for each phoneX_config entry
in the phone configuration file.
I'm not sure if this helps

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?
