PJSIP Inbound Routes, can't distinguish

General Help
1

I have a problem, I cannot distinguish my numbers with PJSIP, in order for any calls to come in I have to have a any DID/any CID inbound route. I’ve tried changing the context, but no luck. I am using a SIP trunk.

Normally on chan_sip for the context I would use

context=custom-get-did-from-sip

and then I would add this code below to extensions_custom.conf

[custom-get-did-from-sip]
exten => _.,1,Goto(from-trunk,${CUT(CUT(SIP_HEADER(To),@,1),:,2)},1)

However this isn’t working with PJSIP. Do I have to edit another file?

PS - I am using FreePBX12 and Asterisk 13.

Thanks, but I honesty don’t know which code block I should be using.

The difference is 'SIP_HEADER" is used for chan_sip, whilst PJSIP_HEADER is used for pjsip. However, I’m pretty sure you DON’T need that. The ‘To’ field, in the header, is the destination of the DID. Have a look at your logs of incoming calls, and it’ll say something like ‘Unkown Destination XYZ’ - that’s the To header.

Here’s an example inbound call that hits the PBX but get number unavailable message.

That means that it’s coming to ‘s’, usually. Do you have a catch-all DID set up? That’ll display the DID in the log. (Create an inbound route with DID and CallerID blank, and that’ll match everything)

My first inclination would be to replace SIP_HEADER with PJSIP_HEADER in your new [custom-get-did-from-pjsip], did you try that?
