Greetings,
We recently upgraded a client IP Telephony infrastructure to CUCM ver 11.5, and added a new IP subnet to the IP phones. After the phones obtain their IP addresses from the DHCP server they automatically register them selves as a DNS entry with their hostname (e.g SEP001122334455).
I consulted a Microsoft Engineer and he advised this might be a feature in the DNS server where the endpoints can add their hostname as an A record, but for this to happen you have to enable the feature from the endpoints.
Any one encountered the same? Is their a feature maybe in the call manager 11.5 that does the same? Also note that this happens in one subnet only not all the subnets.
