Ok, thanks for your help. I configured Option 66 to go to the primary server. On that server, I configured the Primary Registration Server with the domain name. That did the trick.
Now we've got another issue. The phones cannot call each other using the alias. I have 10 digit DIDs for the user and the last 4 digits as an alias. For some reason, when I call using the 4 digit alias, the attendant says that number is not valid. Strange!

The config files configure the phone to look for a sip server in the sip domain (the SIP SRV record lookup).

When I do a dig -T for _sip._udp.example.com (actually using my domain), I get the appropriate records. I'm really not sure how much better to explain our situation. We have two servers and both are running DNS. Our Cisco router is providing DHCP. We are using Polycom phones. I can't understand from reading the documentation exactly how to instruct the phones to look for _sip._udp.example.com. They are never making it to the server to pull a config. How should we configure the DHCP scope, so the phones can pull the necessary information to utilize the DNS SRV records?

SRV is for the domain. When you setup yur system it said the "sip domain" during the second part of your setup. If for example yours is "mydomain.com", then you SRV records should be _sip._udp in windows dns, for domain (zone) mydomain.com. "An example SRV record might look like this in a DNS zone file: _sip._udp.example.com 86400 IN SRV 0 5 5060 sipx.xyzcompany.com. This SRV record points to a server named sipx.xyzcompany.com listening on UDP port 5060 for SIP protocol connections. The priority given here is 0, and the weight is 5." This is an excerpt from: http://sipx-wiki.calivia.com/images/0/0b/SipXecsDNSConcepts.pdf In that document the DHCP options are discussed (like NTP and timezone offset), too. Personally, I prefer sending the IP in option 66 (linux will let you, don't know if windows will), it lets the phone find it's boot server and get its config even if dns is donw, though you cant register or remotely reboot the phone). This really shouldn't be that difficult a task. What exactly are you having problems with? Remember SRV is like an MX record, with extra fields to fill out. When you send email to me, you don't send it to my mail server by name. Sip is the same way, but the records have to be right or you cant send or receive email, I mean, er, calls. DONT's - 1. Register by hostname 2. Register by IP address 3. Continue past go until DNS is working. Can you explain what is not working?
