I'm looking into strange behav. of Cisco 9971 IP Phone.
For example: Today in the morning, I've rebooted this phone and he is registered from 10.91.0.3 IP, but in a few hours when DHCP lease will be expired and if Phone will obtain a new IP from DHCP server, he will try to authenticate on SIP server (CME 8.6) again, but
