[Asterisk-Users] congestion problem with only one number

[Michiel van Baak]

Hi all,

I have this weird problem.
I'm running asterisk 1.0.3 on Debian Sid (official debian package).
We have 2 fritz ISDN cards.
All is working great.
Till I called the bank. It rings one time and then gives me
the congestion tone.
Here is what I see on the CLI (phone nr obfuscated for
privacy reasons):

    -- Executing Dial("SCCP/michiel-00000004", "Modem/g1:xxxxxxxxxx|50|Ttr") in new stack
    -- Called g1:0342426530
    -- Asked to indicate '3' (Dialing) condition on channel SCCP/michiel-00000004
    -- Current tone (36) is equiv to wanted tone (36).  Ignoring.
    -- Modem[i4l]/ttyI3 is busy
    -- Hungup 'Modem[i4l]/ttyI3'
  == Everyone is busy/congested at this time
    -- Sending tone 127
    -- Executing Congestion("SCCP/michiel-00000004", "") in new stack

I only have this with the bank.
Is it possible there is some PBX at the bank that messes up
normal call progress in * ???

This is a Dutch bank, maybe ppl in Holland using * can try
to call the bank. It is the rabobank.

relevant configs:
modem.conf

[interfaces]
context=remote
driver=i4l      ; isdn4linux - an alternative to i4l is to use chan_capi
language=en
type=autodetect
stripmsd=0

The lines in extensions.conf that handle outgoing calls

exten => _0XXXXXXXXX,1,Dial(${TRUNK}:${EXTEN},50,Ttr)
exten => _0XXXXXXXXX,2,congestion
exten => _00X.,1,Dial(${TRUNK}:${EXTEN},50,Ttr)
exten => _00X.,2,congestion
exten => _4XXXXX,1,Dial(${TRUNK}:0342${EXTEN},50,Ttr)
exten => 112,1,Dial(${TRUNK}:112,50,Ttr)
exten => _0[89]00X.,1,Dial(${TRUNK}:${EXTEN},50,Ttr)
exten => _0[89]00X,2,congestion
