[Asterisk-Users] "auto fallthrough" hangup on 1.2.1

[Pisac]

I isolated problem, but I cannot find a cause. I think this is a bug!
So, there is very very simplified dialplan which working in 1.0.9 but in
1.2.1 have that unexpected hangup:

;-------------------------------------
 exten => s,1,answer
 exten => s,2,digittimeout(0)
 exten => s,3,responsetimeout(15)
 exten => s,4,background(ivr-announce)

 exten => 1,1,goto(option1,s,1)
 exten => 2,1,goto(option2,s,1)
 exten => t,1,hangup
 exten => i,1,goto(s,1)
;-------------------------------------

When I press any digit DURING PLAYING ivr-announce (not after announce
is finished), my line hangup:

  == Auto fallthrough, channel 'IAX2/someusername-2' status is 'UNKNOWN'
    -- Hungup 'IAX2/someusername-2'

Where 'IAX2/...' is channel through I connected to IVR. If I connect
through ZAP (ISDN/PSTN) then there is written 'ZAP/...', and if I get to
this IVR context after some dialing of busy number, then ...status is
'BUSY' instead 'UNKNOWN'.

If i change digit timeout to 1 sec:
exten => s,2,digittimeout(1)
then everything working as it should !!!

***************
So, conclusion is that problem with unexpected line hangup occuring only
when digittimeout=0 and some DTMF digit is pressed during playing some
voice file. IS THIS A BUG?
***************

My temporary solution is to set digittimeout=1.

Any comment about this issue?
Cheers.
