All - We moved our demark on Saturday, and had to drop all of our existing PRI and MPLS circuits for the cut-over. Post cut-over, Call Manager came back on-line. Call's were coming in and everything seemed fine. This morning, I'm getting the following error message from my subscribers unable to reach my publisher...

Verify the network between the primary and secondary nodes. Check the status of NTP on both the primary and secondary nodes via CLI 'utils ntp status'. If the network is fine, try restarting NTP using CLI 'utils ntp restart'.

When I ran "utils ntp status", I received this output...

I am noticing a little "static" on or PRI's when I make calls, so this could be a clocking issue. Here is my question: Do I dare run 'utils ntp restart' in the middle of the day, or will this drop calls? What other caveats will I experience? Since this is our clocking, I'm thinking that this will drop calls. I read of problems with Unity after restarting this service.

Any advice would be helpful
 
Well - the answer to my question is "no" - restarting the NTP service will not drop calls.
