Digital Receptionist is not working anymore, just dial tone there

[Simon Schäffler]

Hey everyone,
we have a problem which occured out of nowhere yesterday. We have 3cx Phone System v.14

Normally if a external persons calls our general phone number he will here immediately the digital receptionist, where he can select numbers for a specific destination.

Since yesterday lunch time, you hear the digital receptionist not anymore, but you will hear a ringing / dial tone. There is nothing happening further.. call will not be terminated, forwarded not even pressing a number is working.
I investigating the problem now for 1 day.. maybe there is something screwed up with the Webserver IIS, due to Windows Update. System is running on a Windows Server 2008 R2.

As well we installed SSL certificate yesterday morning on this server, but the phone system was working for a few hours after that process.

Logfile says the following after a call to the general number:

Hopefully somebody can help me with that problem or see's a problem which I can't see at the moment.. Is it a problem to install SSL certificate on the server AFTER the phone system was installed and running?

Thanks in advance,
Simon

Hello @Simon Schäffler

I would recommend upgrading the system to the latest version as soon as possible as you will have issues with activation in the immediate future (you should have received an email regarding this). After the upgrade check if the issue persists.
