[asterisk-users] HANGUPCAUSE() not working in PJSIP for failed calls

[Kingsley Tart - Barritel]

Hi,

This is using Asterisk certified/13.21-cert2, FWIW.


I have a hangup handler on an outgoing SIP channel that grabs the SIP status
like this:

    NoOp(keys=${HANGUPCAUSE_KEYS()} sipmsg=${HANGUPCAUSE(${CHANNEL},tech)})


This works fine if the call connects to the other end but the caller for
example hangs up while it's still ringing:

    NoOp("PJSIP/custom-000000ab", "keys=PJSIP/custom-000000ab sipmsg=SIP 180 Ringing") in new stack


It also works fine if the call was answered:

    NoOp("PJSIP/custom-000000ad", "keys=PJSIP/custom-000000ad,PJSIP/squiresvi-000000ac sipmsg=SIP 200 OK") in new stack


But if the remote end returns an error status (eg 404) then I get nothing:

    func_hangupcause.c:140 hangupcause_read: Unable to find information for channel PJSIP/custom-000000af
    -- Executing [sipdirect2 at hangup_handlers_egress:6] NoOp("PJSIP/custom-000000af", "keys= sipmsg=") in new stack


Any idea whether this is possible? It works fine in our old Asterisk 11
systems, but on Asterisk 13 with PJSIP I'm getting nowhere with it.

Cheers,
Kingsley.
