Dear All
We have clients who have Snom 370 handsets and are in the process of migrating them to 3CX.
We upgraded to the latest firmware which now supports LetsEncrypt (8.7.5.48), assigned the phone to an extension and waited for it to be provisioned. Rebooting the phone didn't help even.
After a number of days of head scratching and combing through log files, we found this error in the Snom log file (I have put in dummy data / MAC addresses):
The Snom was getting HTTP error 500, but downloading https://mypbxname.3cx.co.uk:5001/provisioning/kfndu3io03jf/cfg000413AD440A from a web browser worked perfectly, which proved it wasn't a firewall issue.
It seems that 3CX now has the following feature turned on by default (in Settings > Security > Anti-Hacking), which makes 3CX more secure but stops the Snom 370 from being able to download the config files. I assume that this is because even the latest firmware doesn't support TLS 1.2.
Once you turn this off and restart all of the services, the provisioning works perfectly.
Hope this helps others
Regards
John
