CUCM/CUC Second NTP Server

[jason.henderson]

I'm looking at a client UC setup at the moment, and the NTP reference for CUCM and CUC is a lab one that is now inaccessible.  I don't want to remove and change this because I'll have to go through the licencing again.

My question is - can I add a second one and keep the licencing fine?  Version 8.6(4)SU2.

Thanks in advance,

Jason

Hi Jason,

I remember we can add five external NTP servers in Cisco Call Manager  version 6 .x and cisco recommends at least three.

Not sure about call manager version 8

Hi Jason,

Yes, you can add another NTP server and it will have no impact to licensing. I've tested this on UCM 8.5 in the past.

HTH.

Just took the plunge and added a second NTP reference to CUC and it's working fine, no licencing issues.

Cheers!
