Yealink T-54W not getting date/time.

[Robert O'Rourke]

We're setting up a new phone system and after provisioning the Yealink T-54W phones they have an incorrect date and a time of 12:00. Port 123 UDP is opened on the firewall. Time zone was set to Central US on the provisioning page. The latest firmware was updated a couple of days ago. I brought one of them back to our office, did a factory reset, and provisioned it on our phone system. As soon as provisioning is complete it has a time of 12:00. It's the only phone on the system that is not pulling the correct time and date, but it is also the only T-54. All of our phones are either T-42S or T-46S.

Hi there.
The phones will get the time from the NTP server: pool.ntp.org as this is what will be set in the phone template once it gets provisioned. So the phones should have the ability to communicate with that server.
See your network there and if it has any limitations, and if so, allow that communication with the NTP server.
