Solved T54W - Incorrect time

[JSlow]

Not sure what happened but it seems like (so far) my phone is showing the incorrect time. I can confirm it has the right NTP information and the 3cx server has the correct time also. I also verified that the subnet the phones are on can reach the NTP servers.

Things I've tried:

1. Rebooting the phone
2. Factory reset
3. Downgrade firmware (did not work phone reported a failure.)

I can set the date & time manually but that just gets wiped when the phone reboots or get reprovisioned. Any ideas would be greatly appreciated. Thanks

I figured it out.

In our configuration, the pbx is hooked directly into our ISP gateway to avoid any firewall issues that typically happen with VoIP (Especially with SonicWall. I forgot we did this). However our phones are configured to use our firewall as the gateway. For whatever reason, our firewall suddenly decided to block DNS and NTP. Making ALLOW rules for DNS and NTP fixed the issue.
