Solved forwarding rule problem

[bashrael]

Hi we have a 3cx cloud server with 3 remote stun extension on 1 site.

Incoming calls work ...extension starts ringing. But after 30 seconds the call should be forwarded to a group with the 2 other extensions.
The forward doenst happen en the call just ends.
I can't find what is causing this.
This is the log:

Who has this IP? Have you tried any other forwarding from the Extension, does that work?

 

[bashrael]

Hi, thats an ip from the sip provider.
No not yet tried that. There only 3 extensions in this 3cx pbx. But i could try to forward to an extension instead of a ring group.

 

[bashrael]

IIf we change the forwarding time from 30 sec to 15 sec the forward works.
If change the time to 30 sec again the call ends after 30 sec.
What could this be?

the provider is ending the call before your timeout expires if the above is indeed correct

 

[bashrael]

I tried forwarding to an extension in stead of a group and the result is the same.
I sended a log to our provider to check out whats happening on their side

 

[JohnS_3CX]

Ok, let us know what the provider responds

 

[leejor]

Your provider will have to confirm, but it would appear that they terminate unanswered calls after a set time. I have seen some do this to prevent lost calls, that simply remain "up", for some reason, tying up resources. Hopefully they can increase the time for you.

 

[bashrael]

Hi all,
So it was the sip provider.
After 30 seconds they sended the call to failover.
After adjusting this everything works fine now.
Thanks all.

Glad to know it has been resolved
