Sip server keeps going down

[sigmaIT]

I have some 15 more or less identical installations, on one fully updated v18 install of 3CX, PhoneSystem 01 SIP Server keeps on going down once or twice a day, anyone any suggestions how to resolve or troubleshoot?

As @kieferschild mentioned, please do provide more information regarding this setup : https://www.3cx.com/community/threads/information-to-provide-when-requesting-help.67558/

Also, make absolutely sure that the machines resources usage is normal and that the instance complies with our hardware requirements: https://www.3cx.com/docs/recommended-hardware-specifications-for-3cx/

If it is the SIP Server that's dropping, more often than not it's be due to a loop. Check your call routing configuration and make absolutely sure you are not unintentionally creating any loops such as having a call queue routing to another Call queue that routes back to the first call queue, etc. 3CX has built-in mechanisms to detect loops and terminate them, but, depending on the configuration they might still cause issues in certain situations.

You might want to consider running a call report for the time right before the SIP service crashed and give it a look through. If there's a call loop or anything problematic it should be apparent in the report.

Have you looked at the 3CX Activity Log, to see what was happening, just before it dropped? Does this happen at the same time each day, is there a pattern?
