I have a IVR with options that forward all call’s to external numbers:
One of the options have a ring group with many numbers with five digits “XXXXX” and work’s without problem.
Another option, has a external number with 3 digits “20X” and never works, in booth situations, when I define a ring group with just this number or a Custom Application with the number in code and define the external outbound route in Destination, like this:
Every time I received this error when the IVR arrive to this number:
[2022-06-21 12:21:23] WARNING[8409][C-00000051] pbx.c: Channel ‘PJSIP/75003-00000089’ sent to invalid extension but no invalid handler: context,exten,priority=trk-group-10,0,1
I feel like most of these issues are basic routing logic that you have to learn.
We can either feed you, or teach you how to fish.
I think that your next step should be a visual routing diagram so you can understand yourself the routes, rules, pattern matching and destinations so you can understand it yourself. Once it clicks, you’ll come up with the best solutions to fit your environment.
