I have a ccm 7 pub and sub which is replicating changes to each other without any problems.
However, we I try to create a DHCP server on the Sub I can't register a 7960 phone. The phone show 'defaulting cm to tftp server' followed by 'phone registration rejected'
If I manually disable DHCP on the phone and point the tftp server to the Pub, the phone gets registered.
For fault isolation, the pub, sub and the phone are all connected to the same switch.
Any advice appreciated.
