CUCM 6.1.5 Set local time and not use NTP server

[Jay Matrona]

Hello

The time on all the handsets in our office are off by 6 minutes even though they are pointing to an internal NTP server that has the correct time.

I want to just remove the NTP and set the time locally on the CUCM?  Either command line or web UI instructions are fine.  Another question is, After the time is changed, is there any way to push the change down to the phones without a reset so calls are not interuppted?

Thanks

Jay

Not all phones use NTP directly.  Many phones get their time from CCM.  Mainly, it's the high end phones that use NTP on their own.

You can use the command utils ntp status to see what's going on between CCM and NTP.  But if the phones are models that get their time from CCM, simply updating the time on CCM will fix your issue.

I meant NTP from CUCM not the phones getting NTP directly.  My question was not written well =(

I know that the CUCM is pointing to an internal server for NTP.  But it is not working.  So, I am looking for the proper steps to:

1. remove the NTP settings

2. Set local time on the CUCM  *not point to NTP server

3. Push correct time out to phones

What stratum is your NTP time source?  I've found that CUCM really likes low stratum numbers, and higher ones may not work. 

If you have a stratum 2 or 3 source in your network, those tend to be bulletproof.

Thanks for the responses Cliff.  Here is info re: NTP  The stratum is 11(?!)  How do I get that down....especially when it is pointing to an internal server?

This node is configured to synchronize with one of the following NTP server(s):

  10.1.0.12

[Clifford McGlamry]

Hmmm....10.1.0.12 isn't synced to an external source (according to your output).  But your server isn't synced to it anyway.

Try doing an UTILS NTP RESTART

That will force it to reset. 

What is 10.1.0.12?  Is it a router/switch?  Is it synced against an external source?

[Giovanni Ceci]

That address is actually the IP of the CUCM. And it looks like you are not using any NTP source at all. That is what you were going for?

That IP is of an internal server that gets NTP updates from outside source.

Log into OS Administration

Go to Settings > NTP

Delete the NTP Source

Then if you want to set time manually go to

Settings > Time

Otherwise if you want to add a working NTP source go to

Settings > NTP > Add New

Reset 1 phone to check it has the correct time

If still not working try UTILS NTP RESTART from the CLI
