> https://wiki.asterisk.org/wiki/display/AST/Asterisk+13+Application_Stasis. I noticed there is a handy variable named {code}${STASISSTATUS}{code} returned when Stasis is finished (OR fails). However if I never register my stasis application and dial into the context where stasis is at once Asterisk hits stasis and realizes it can't talk to said app Asterisk just hangs up on the channel. I was hoping to be returned to the dialplan to be able to run a failover destination.
> Quick Dialplan:
> {code}
> [ari-trunk]
> exten => 45,1,Noop(Attempting to join test ari)
> exten => 45,n,Macro(user-callerid,)
> exten => 45,n,Stasis(test,45)
> exten => 45,n,GotoIf($[${STASISSTATUS} = "FAILED"]?from-did-direct,1000,1)
> exten => 45,n,GotoIf($[${STASISSTATUS} = "SUCCESS"]?app-blackhole,busy,1)
> exten => 45,n,Answer
> exten => 45,hint,Stasis:45
> {code}
> CLI:
> {code}
>     -- Executing [45 at from-internal:3] Stasis("PJSIP/1003-00000001",test,45") in new stack
>   == Spawn extension (from-internal, 45, 3) exited non-zero on "PJSIP/1003-00000001"
>     -- Executing [h at from-internal:1] Macro("PJSIP/1003-00000001","hangupcall") in new stack
> {code}
> I propose to more gracefully handle this and just return to the dialplan so the creator can do something appropriate instead of just having Asterisk hang up the channel
