Outbound call timeout

[daktur]

I have setup a new provider however, sometimes the outbound call attempt times out without getting connected.

My provider reviewed and looks like normal on their end. Is it possible to extend the duration of the attempt before timimng out?

Thanks!

Hello @daktur

Please note that 3CX will drop the call after 32 seconds if no ACK is received which cannot be changed. Does the call time out while it is ringing or is it dead air? And where is call getting dropped from? Do you see the BYE message from the 3CX side?

Hi @YiannisH_3CX ,

Tha call fails dead in the air.

This is the log for the call that failed:
01/06/2018 2:42:01 PM - Call to T:Line:10002>>000005511981934567@[Dev:sip:<IP>@sip.<PROVIDER>.com:5060] from L:3112.1[Extn:001] failed, cause: Cause: 480 Temporarily not available/INVITE from 77.72.174.128:5060
01/06/2018 2:42:01 PM - [CM503003]: Call(C:3112): Call to <sip:000005511981934567@sip.<PROVIDER>.com:5060> has failed; Cause: 480 Temporarily not available/INVITE from <IP>:5060

But for other numbers it works just fine.

Looking forward to hear from you.

Thanks,
Ariel.

Cause: 480 Temporarily not available

This indicates just what it says. That number is not available, for some reason. The message is sent from your provider. They probably won't be able to provide any additional information as they will see the same message to whoever they pass the call onto.

as leejor mentioned this message originates from your provider indicating that the number is not available. The only thing you can do from your side is to make sure that the dialled number is correct.
