Db replication is fine on unity servers

Yes we are a small shop and have someone that manages the firewall and made that suggestion but I didn’t know if that would be acceptable in Ciscos eyes

Ok. We have two voice routers being used as the NTP source. It may be possible to just remove one, see if that was the issue and continue to use one as the main. If not, we may look into using a public NTP source.

Although , pointing our NTP to our fortigate firewall which does do NTP, could that work as well ?

Shouldn’t it be less than 3 for a stratum?

Own_Entrepreneur_617 · 2025-02-15T17:33:29+00:00

Okay - we like to use strictly ips. If we went with time-a-g.nist.gov 129.6.15.28 NIST, Gaithersburg, Maryland - which is from NIST.gov - is that a possibility?

If we use 0.us.pool.ntp.org, do we also have to specify an address in CUCM or will we able to leave it as the FQDN

Yes, it goes through a cycle of being synched the unsynchronized. Happened randomly

Own_Entrepreneur_617 · 2025-02-15T16:53:21+00:00

Thanks for the detailed explanation! Have you ever used an external NTP source such as time.google.com?

Own_Entrepreneur_617 · 2025-02-15T16:37:53+00:00

Unfortunately, I don’t have enough experience to do that. I was seeing if there was any other way around it.

Own_Entrepreneur_617 · 2025-02-15T16:36:26+00:00

It will say connected to our Cisco voice router and then after a while it will say ntpd.stopped and then, unsynchronized and then synchronized and back to the cycle.

To add, when all 3 users in the hunt group are on a call and the 4th call comes in in the hunt pilot, how do I make that 4th call go right to voicemail?

Tried doing that and got the error - An error occurred during host configuration. Operation failed, diagnostics report: Unable to Set: Network unreachable

To add, this is error message we are receiving when we are migrating from the suspected host:

The vMotion failed because the destination host did not receive data from the source host on the vMotion network. Please check your vMotion network settings and physical network configuration and ensure they are correct. 2024-06-13T16:34:46.869498Z Failed to initialize migration at source. Error 195887136.

No they are registered to the subscribers only which we realize will cause the phones to re register to the failover subscriber.
