Description:Asterisk after last h ext priority suddenly start execute _. ext from next priority number.
Sample dialplan to reproduce:
{code}
[ivr]
exten => _.,1,Answer
   same => n,Set(isstored=1)
   same => n,Set(LIMIT_PLAYAUDIO_CALLER=yes)
   same => n,Set(LIMIT_WARNING_FILE=beep)
   same => n,agi(/etc/asterisk/agi-timelimit-and-subscribe.py)
   same => n,hangup()

exten => h,1,NOOP(timelimit hangup isstored=${isstored}, call_id=${id1})
   same => n,GotoIf($["${isstored}" == "1"]?end)
   same => n,AGI(/etc/asterisk/timelimit-hangup.agi)
   same => n(end),Noop(hangup timelimit end)
{code}


Dialplan debug:
{code}
   -- Executing [123@ivr:1] Answer("SIP/101-00000024", "") in new stack
      > 0x7fc18c016660 -- Probation passed - setting RTP source address to xxx

 == Spawn extension (ivr, 123, 5) exited non-zero on 'SIP/101-00000024'

   -- Executing [h@ivr:2] GotoIf("SIP/101-00000024", "1?end") in new stack
   -- Goto (ivr,h,4)

   -- Executing [h@ivr:5] AGI("SIP/101-00000024", "/etc/asterisk/agi-timelimit-and-subscribe.py") in new stack

   -- <SIP/101-00000024>AGI Script /etc/asterisk/agi-timelimit-and-subscribe.py completed, returning 0
   -- Executing [h@ivr:6] Hangup("SIP/101-00000024", "") in new stack
{code}


As we see here, it should stop at h@ivr:4, but it execute non existing h@ivr:5 and h@ivr:6, which is _.,5 and _.6.
agi just stream one audio in that case, do verbose output once  and exit with agi hangup

This is not a bug. This is the way the dialplan works, when the next priority is moved to it will find the next closest match.

Please look again at my post. There is no next closest priority in h, 4 is last. Call ended channel was hangup.
Or h matched _.?

h matched _. which is why when you use it a warning is output on the console.
