v3000r and NTP

We have set the NTP on the v3000, but time still drifts.

We have two seperate systems (diff cities), set to the same NTP and both are off by different degrees. Code is 6.0.49 Why the drift?

Re: v3000r and NTP

What kind of phones are drifting?? Is it all of them or is it IP Phones?

The NBX gets the time from NTP, then distributes it to the phones via a multicast packet. I would believe that it may be IP Phones that are not getting the time and your router is not passing the multicast packets.
