How do I make newer Cisco phones use domain instead of IP?

Posted:Mon 12 of May, 2014 (16:47 UTC)
I have several Cisco 8000 and 9000 series IP phones using SIP firmware on a non Cisco proxy server. In the configuration file for the phone, I use a hostname as the proxy server but the problem is the phone resolves the hostname to an IP and sends the REGISTER and INVITE messages with the IP in the sip message instead of the domain. How can I force it to use the domain/host?
