When I do a new install, the phones don’t show up the right time. After doing a wireshark trace, I can see the NTP packets are going through the switch to the phones, but the phones don’t accept the right time from the DHCP server(option 42 and option4 are both configured correctly on DHCP server). The phone show an initial date of Feb 6, I have rebooted the DHCP server, phone server, phone switches and IP phones, but no luck.

Sounds like it should be working. The only thing I could suggest is to ensure that the NTP server addresses you entered into the DHCP server are working. Internet time servers are notoriously slow and unresponsive. When I set our phones up I had to check several servers before I found some that responded in a timely fashion.

DHCP servr option 4 and option 42 are configured on the Shoretel Phone server to give out IP addresses and also the time in the scope.
The Shoretel Phone server (Windows 2003) is getting time internet (time.windows.com)
The zone is also correctly set. Can someone suggest where can I change the Stratum level on the Shoretel Phone Server. Thanks

Make sure that the router ip address (option 3) is configured correctly as well. It should be the same as the "gateway" IP address that is shown by ipconfig on any of the pc's that has internet access.. I had the same problem when I first setup our office phones.

Ntp
Is this something that was working and stopped, or something that has never worked?
If you are pointing to your Voicemail/Shoretel server for NTP time you have to be running/allowing NTP server functions on that server. I do not believe they are on by default.
You also have to make sure the phones can access the server on port 123 UDP
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\W32Time\Parameters registry subkey.
From the Edit menu, select New, DWORD Value.
Enter the name LocalNTP, then press Enter.
Double-click the new value, set it to 1 to enable or 0 to disable, then click OK.
Restart the computer for the change to take effect.
net time /setsntp: will allow you to set which external servers you want to pull time from on the shoretel server.

Hi eazeaz
Can you pl tell how to make allow NTP server functions on that server?
I have enabled DHCP options 42 and 4 on the server.
Do I have to do anything else. Where do I have to enable
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\W32Time\Parameters registry subkey
Thanks

It really does work quite well

Stupid Windoze Time does not work.
