hi all,
I have a strange problem on the cisco ipphones.
The ipphones have already an ip address and registred on the CUCM. but they releases there ip address randomly and frequently !!!
After a while , the ipphones get anther ip address and register again.
Firstly i thought that may be the problem is the Firmware version used by the ipphones --> I tried many version but the problem stil exist.
The CUCM version is : 8.0.3
The LAN is a third party switchs ( hp).
Would you mind to help ?
thanks in advance
Regards
CHAM
