Time on handsets wrong (but systems status correct showing OK with SNTP)

[g18c]

Dear all, we have setup IP Office R9.1 to pull its time from a local SNTP server and it is syncing from the server correctly (time verified with system status).

The phones however are a couple of minutes out on their display, the time is not the same as the system.

Any ideas please? Do they phones pickup any SNTP from DHCP scope (which may be incorrectly configured), or can we force phones to use time from the IP Office Manager.

Set the time to none. Give a user phone user right level 2. Give them a self administer button. Get them to set the time manually.

5410 – Button and system phone set

1. Press Self Administer button
2. Enter extension number as password
3. Select Time option
4. Enter numbers manually with * as colon between hours and minutes

14xx/16xx/95xx/96xx – Self Administer set

1. Press Features
2. Select Phone User
3. Select System Admin
4. Enter extension number as password
5. Select Time option
6. Enter numbers manually with * as colon between hours and minutes

This will then force the system time back to normal. You can then set the time back to the NTP server.

Also what time server and what DNS are you using on the phone system, had an issue before where the DNS server was slow responding and caused the time on the system to flake out a by a few minutes.

Many thanks Manie3, phones are out by 30 seconds or so - is this because 1608-I refreshes time every 30 seconds (picking up handset and putting down updates the time instantly).

Not an issue, just need a reference so i can fire back at customer for reason on difference

I think the system only sends hrs & minutes to the handsets so can be out but up-to 60 seconds.

The IP Office is a PBX not a clock ;-)
