[cisco-voip] Communication Manager 7 and DNS

[svr.file at gmail.com]

Hi,

I have a question regarding CUCM 7 and DNS.

The CUCM 7 servers were configured with DNS, although within the GUI the
server names have already been changed from hostnames to IP addresses.

CLI Output:
DNS
Primary      : 1.1.1.1      Secondary  : 1.1.1.2
Options      : timeout:6 attempts:3
Domain       : xyz.com
Gateway      : 1.1.1.254 on Ethernet 0

This was identified when we notice the CallManager service was not running,
when we manually started the CallManager service, after about 5 minutes the
service would stop. To troubleshoot this further we started RTMT and ran the
Real Time Trace > View Real Time Data report, but noticed an error when
trying to run it. RTMT's error said *"Could not connect to 'Server :
cucm01.xyz.com'."*

My assumption is that the CallManager service is also failing due to not
being able to connect to the DNS server.

Will the *delete dns* command remove the DNS reliance on CUCM servers? Is
there another way to remove DNS reliance on the CUCM servers?

Thanks
