On April 16, between 2:25 P.M. ET and 4:12 P.M. ET, the domain zoom.us was not available due to a server block by GoDaddy Registry. This block was the result of a communication error between Zoom’s domain registrar, Markmonitor, and GoDaddy Registry, which resulted in GoDaddy Registry mistakenly shutting down zoom.us domain. Zoom, Markmonitor, and GoDaddy worked quickly to identify and remove the block, which restored service to the domain zoom.us. There was no product, security or network failure at Zoom during the outage. GoDaddy and Markmonitor are working together to prevent this from happening again.

We have reviewed the firewall settings recommended by Zoom and don't see any issues.

We're using Yealink T54W phones. Device firmware is 96.86.3.12.

If the phone shows as offline (both on the display and in the Zoom Phone admin console), when you re-provision it through the on-screen settings, it comes back online.

Sometimes the phone will remain for hours online, then go offline.

hi rpearson,

 

intermittent issues are hard to trouble shoot.  might be a network issue or could be a yealink issue.

 

are you using wifi or wired connection?

 

you might try plugging the phone into another ethernet connection and see if that stops the issue.

 

i would open a ticket with yealink.

 

Did my response answer your question? If so, please don't forget to mark the reply as an accepted solution.

 

thanks,  eliot

Thank you for the suggestions Eliot.

The error is 'User unregistered', and I have found a few other reports of this issue with the Yealink T54W phone. There are a couple of network settings that might affect this, but so far I have whitelisted the recommended Yealink URLs in our firewall and updated the firmware.
