Freepbx noob here. We had outbound calls working, and then all of a sudden we started getting this:
app_dial.c: Called PJSIP/9876541230@Livingston-Vitelity-543-210-4567
app_dial.c: Everyone is busy/congested at this time (1:0/0/1)
Executing [s@macro-dialout-trunk:34] NoOp("PJSIP/3325-00000061", "Dial failed for some reason with DIALSTATUS = CHANUNAVAIL and HANGUPCAUSE = 21") in new stack
On the line it says, “All circuits are busy. Please try again later.”
Here’s a screenshot of my Outbound Route settings:
This is not an outbound routes issue. From the tiny bit provided we can see the dial was attempted on the trunk, and the provided did not terminate the call.
Well one of the reason becomes from cause release code indicated on verbose as “call rejected” therefore you need to check with trunk provider support.
By the way on capture file it seems have trouble with registering SIP trunk it could presume all problem could becomes from the same reason, so you should see with your sip trunk services.
Good luck.
