Richard Mudgett updated ASTERISK-27666:
---------------------------------------

    Attachment: jira_asterisk_27666_v13.19.0.patch

[^jira_asterisk_27666_v13.19.0.patch] - This does the minimum to prevent the crash and may be all that is really needed.  I haven't setup a SIPp scenario to confirm.

Apply {{patch -p1 -i jira_asterisk_27666_v13.19.0.patch}} to see if it fixes the crash.  We cann't do anything about the provider messing up the SIP transaction but we shouldn't crash as a result.

> I usually log the HANGUPCAUSE when the Dial command doesn't succeed. I discovered, with one particular provider, it crashes asterisk. Here the simple asterisk dialplan:
> {noformat}
>         9999 => {
>              Dial(SIP/999383371137 at crashprovider);
>              NoOp(This is CallEnd - DIALSTATUS is ${DIALSTATUS} - HANGUPCAUSE is ${HANGUPCAUSE});
>              }
> {noformat}
> In attach, you'll find the crash report and the pcap for the traffic with the server. The call was made from extension 103 (103-DEVEL)
