Hi!  I have three Cisco phones for my tests, a 7960, 7965, and 7975.  The 7965 is OK, but the 7960 and the 7975 can't register.


Is there something special that needs to be done for these phones to register?


When doing a WireShark trace, I noticed that the configuration has "USECALLMANAGER" for some of its values, and the phone seems to be using that literally.

 94  45.110356 -> DNS 84  Standard query 0x0023 SRV _sip._udp.USECALLMANAGER
 95  45.288820 -> DNS 159  Standard query response 0x0023 No such name SRV _sip._udp.USECALLMANAGER SOA
 96  45.291135 ->      SIP/SDP 835  Request: INVITE sip:1101@USECALLMANAGER | 

If I manually set some of the information, then the phone can work.

Where do I set this information in the server?
