3cx Crashing randomly

[GH-JD]

Hi,

So we have a 3cx phone system hosted in azure connected to our MPLS via Expressroute, we also have SIP trunks connected.

Randomly users phones will stopped ringing, sometimes say no service in the top left, sometimes they just dont ring.

The customer calling in hear's our on hold music and goes through the different overflows then eventually to voicemail.

Most of the phones are connected via SBC

Has anyone else experienced this problem within the Phone system?

Regards

Matt

Please provide more info on the setup - https://www.3cx.com/community/threads/information-to-provide-when-requesting-help.67558/

What steps do you do, to get the system back online

 

[GH-JD]

3CX Version - Enterprise Annual 16.0.611
Server OS - Linux (Debian 9.11)
Hosted - Azure
IP Phone - Yealink T48s (66.85.0.5) / T46s (66.85.0.5)
Provisioning Method - SBC
Has the Firewall Checker passed - YES
Are custom Phone Templates being used - NO


When it happens, i just reboot the azure VM and it begin working again.

As I understand are you using Yealink -> 3CX SBC -> MPLS - > Azure -> 3CX
We need to shorten the possibilities as I personally have never used Azures ExpressRoute.

In this moment, does the 3CX Management Console or the 3CX WebClient still function by calling then FQDN or the IP in a browser? Does and 3CX Phone (iOS or Android) at that moment still function normally?
