> Unfortunately, not much debugging information available. That was one of a kind error. The following AEL code has been executed with errors appearing between 2 trace lines:
>     &trace(Entering queue - ${QUEUE_STATS}); //<- after this
>     &answer-nocdr-maybe();
>     Queue(${CUSTAPPRAW},ct,,,${QUETIME},,,on-queue-answer);
> . . . 
> macro on-queue-answer() {
>   &trace(Answering in $[${CDR(duration)}-${CDR(billsec)}]s on ${CHANNEL}); //<- before this
> }
> The call had been answered in the macro
> macro answer-nocdr-maybe() {
>   if("${CHANNEL(state)}" == "Ring") {
>     Answer(0,nocdr);
>     Wait(0.5);
>     Ringing();
>     Wait(1);
>   }
> }
> ****** ADDITIONAL INFORMATION ******
> Context:
>         ast_channel_ref(owner);
>         sip_pvt_unlock(p);
>         ast_channel_unlock(owner); //<--- here
>         *nounlock = 1;
>         pbx_builtin_setvar_helper(owner, causevar, causeval);
> I am sorry, this report is very vague. Still I thought it might be worth logging.
> Might be related to ASTERISK-1815403. Just a gut feeling.
