Solved Phones stopped registering

[josephreto536]

Hi! I have 8 virtual machines running because i own a store and recently the cisco 7940s stopped working at the 8 locations. The phones are stuck on registering. What can I do to fix the issue? Heres a picture of the store phone for proof.
Thanks. Joseph,

A bit more information about your setup might help...

Were there any recent changes to firmware, upgrades,or your network?

 

[josephreto536]

Yes, i updated the firmware last month. And the phones was working yesterday. My 8 servers are running Debian 9 on AWS and the version is V18. The IP address is local. The custom phone templates have not been used. Nothing about the phone appears on the firewall.

Version 18 on runs on Debian 10 , are you sure you are running Debian 9

It will not be an easy task to troubleshoot all those sites, and the Cisco 7940 cannot run with machines in AWS natively.

If you have so many locations and they are all down, you might benefit from contacting a 3CX Partner to help you.

Hello! So i gave my 3cx partner access to the server via putty. And it was the firewall blocking the department phones on each server and I've whitelisted the IP addresses on all of the servers. And i told all of the managers to reboot the phone and the phones started working again. Thanks for all your help!
