CUCM & CUP DNS and Domain name

[jack samuel]

Hello

CUCM 9.1, CUP 9.1 and CUC 9.1

I have not mentioned DNS or domain name on my CUCM and on my CUP, if i enable the DNS and domain name on the CUCM does it will change the license mac of CUCM AND CUP ???? which will cause me to rehost the license from the cisco licensing team.

thanks

CUCM 9+ don't use a license MAC.

Dear Aman,

Hi Jack,

Not aware.

See if anybody can help us.

Changing the domain name settings will cause CUCM to generate a new self-signed Tomcat certficate. But the other ones shouldn't change.

Dear Gordan,

This TOMCAT certificate is for accessing the CUCM through WEB where we get a security alert correct me if i am wrong??

Any where else  it can be affected such as for internal communication to unity connection and unified presence or to extension mobilty

thanks
