Phones not getting correct time

[TSlocum]

We've got Cisco SPA514g phones and when they auto-provision with DHCP Option 66, they don't get the correct time. They show 1/1 12am. The time on the server is correct and the time zone is set correctly in the provisioning options.

What could be causing this?

We were having the same issue but I found the resolution

Assuming your phone is provisioned with the right Provisioning Template, do the following:

3CX Phone System - Settings - Phone Provisioning
Enable Day Light Savings Time

I am in Australia, so these are my StartTime and EndTime

StartTime: Month: 10 - Day: 4 - Hour: 0
EndTime: Month: 4 - Day: 3 - Hour: 0
Offset(Minutes): 60


Save the settings and re-provision your phone from

3CX Phone System - Phones - Re-provision Phone

Good luck

I tried that and it didn't work.

Check the management console
Settings
Phone Provisioning
Time Settings
Time Server

default is
pool.ntp.org

This should be provisioned and be visible in the phone web interface and this is where the time should be coming from, along with your time zone modification and dst. If you are not getting a good date then you are probably not getting to a good time server.

I've tried pool.ntp.org, 0.us.pool.ntp.org (another ntp pool server here in the US), and the local DC, none of which work.

Might want to examine your firewall(s) to make sure they are not blocking ntp traffic.

My Cisco 7960s would never pull the time info from 3cx server (v12). I had to hard code it in their template, which seems to be working fine now. You phones are much newer than mine, but this is what worked for me...

#Setting for Timezone and DST, Option GMT,CET,EET,...
sntp_server: "10.10.10.65" (internal ntp server)
sntp_mode: unicast
time_zone: "%%param::time_timezone_cisco79x0%%"
dst_offset: 1
dst_start_month: March
dst_start_day_of_week: Sun
dst_start_week_of_month: 2
dst_start_time: 02
dst_stop_month: Nov
dst_stop_day_of_week: Sun
dst_stop_week_of_month: 1
dst_stop_time: 02
dst_auto_adjust: 1
time_format_24hr: 0
date_format : M/D/Y

First off, make sure NTP is defined and setup properly in the DHCP server settings. Next, use an internal NTP server versus a pool/public NTP server. Some phone are picky about resolving to external pool/public NTP servers through a firewall. Try using the IP address instead of the FQDN. This will eliminate any DNS issues you might have. Finally, don't use the 3CX out-of-the-box provisioning template for your phones. You can create a custom value that changes your daylight savings time without the need for micromanagement. For instance, we use (with our SPA504G):

<Daylight_Saving_Time_Rule group="Regional/Miscellaneous">start=3/8/7/02:0:0;end=11/1/7/02:0:0;save=1</Daylight_Saving_Time_Rule>

This setting adjusts the time changes automatically without the need of defining them every year in 3CX.
