I am using a callmanager 4.1. I know that this CMM does not use device licenses. I used to have about 40 Ip Phones registered on the Callmanager. At a time, some of the phones started configuring IP "CONTINUOSLY" for days and when I try to add new phones, they dont register on the CMM. What are possible remedies for this. Please help.

There could be numberous reason why IP Phones fail to register. DHCP being one of them.
Take a look at this troubleshooting document it details various aspects to investigate:-

Hi Peter,
Just to add a personal touch to the great tips from Allan (+5 points here Allan)
We just had a problem with our off-box DHCP Server and these are the exact symptoms we experienced.
Cheers!
