[Asterisk-Users] IVR problem from PSTN phone

[Andrzej Radke]

Hello all !

I have a problem with my IVR  with terminate connection from PSTN phone 
Here is my configuration

extension.conf
[ivri]
;exten => s,1,Wait(1)
exten => s,1,Answer
;exten => s,2,DigitTimeout(5)
;exten => s,3,ResponseTimeout(10)
exten => ivr,1,Background(demo-congrats)
exten => 1,1,MP3player,/mnt/linux/mp3/song/04.mp3
exten => 2,1,MP3player,/mnt/linux/mp3/song/02.mp3
exten => 3,1,MP3player,/mnt/linux/mp3/song/01.mp3
exten => h,1,Hangup

When I call from Internet using SIP i can chose everything what I want
but I have to press keys 1 or 2 or 3 twice for change my song
Why ?   
The termination this connection is good

When I call from PSTN I can chose everything what want but I have this 
same problem with amount pressed butons (also twice)
Addictionaly I have a problem with terminate this connection
When I hang up the port on my VoIP/Gateway (C2600 + FXO ) is still busy.

  == Spawn extension (ivri, h, 1) exited non-zero on 'SIP/sips-f970'

After ca. 8 minutes his state is correct -> IDLE

What can I do for terminate my connection when it is really ended ?
