[cisco-voip] 7905 is searching non existing DHCP

Sounds like the phone is requesting to renew that IP address with the 
local DHCP server.
In the case of Microsoft DHCP server, it will almost never issue a DHCP 
NAK.  If the phone does not receive a DHCP NAK, it will continue to use 
the cached address until the cached address lease expires.

To clear this condition, go under settings and release the current DHCP 
address.
