[asterisk-users] Issues after upgrading from 1.2 to 1.4: hangup immediately

[Jean-Yves Avenard]

Dear all

I am trying to upgrade our asterisk from 1.2 to 1.4.x

There is something that now fails to work, reading the various
documentations, I can not explain why.

Here is an extract of my extensions.conf

[welcome]
exten => 299,1,Answer                   ; Answer the line
exten => 299,2,Set(TIMEOUT(digit)=5)            ; Set Digit Timeout to 5 seconds
exten => 299,3,Set(TIMEOUT(response)=10)                ; Set Response
Timeout to 10 seconds
exten => 299,4,BackGround(welcome)     ; Play Welcome to ...

include => internal-sip

exten => t,1,Goto(0,1)          ; If they take too long, go back to default
exten => i,1,Playback(invalid)  ; "That's not valid, try again"
exten => i,2,Goto(s,2)          ; try again

----

However, right after playing welcome, it will hangup !
this used to wait 10s then fall on the extension t

This is what I see on the console:
   -- Executing [299 at welcome:1] Answer("Zap/5-1", "") in new stack
    -- Executing [299 at welcome:2] Goto("Zap/5-1", "|s|1") in new stack
    -- Goto (welcome,s,1)
    -- Executing [s at welcome:1] Set("Zap/5-1", "TIMEOUT(digit)=5") in new stack
    -- Digit timeout set to 5
    -- Executing [s at welcome:2] Set("Zap/5-1", "TIMEOUT(response)=10")
in new stack
    -- Response timeout set to 10
    -- Executing [s at welcome:3] BackGround("Zap/5-1", "hello") in new stack
    -- <Zap/5-1> Playing 'transfer' (language 'en')
  == Auto fallthrough, channel 'Zap/5-1' status is 'UNKNOWN'
    -- Hungup 'Zap/5-1'

Any ideas?
Thank you in advance
