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.

Dear Nipun,
The server is configured with IP not FQDN.
The attached screenshot shows the DNS A record entries not LOG file. They appear in the Microsoft DNS Server.

That’s exactly my issue, why there is IP phones hostname A record in the DNS server without me adding them?
