asterisk users - Aug 2007 - Telco is not detecting HangUp w/ TDM400P

Hi guys,

I spent a couple of hours in Google, but the problem 
appears to be uncommon, so I'd like to ask about it here.

The problem is exactly the opposite to "Asterisk does 
not detect FXO hangup". In my case it's the Telco who 
does not appear to be detecting Asterisk's hangups.

Telco is Telus in Vancouver, Canada. The setup is very
simple -

 Telco -> FXO/TDM400p -> * -> softphone

The log is -

    -- Starting simple switch on 'Zap/4-1'
    -- Executing [s at incoming:1] Answer("Zap/4-1", "") in
new stack
    -- Executing [s at incoming:2] Dial("Zap/4-1",
"IAX2/alex|5|r") in new
stack
    -- Called alex
    -- Call accepted by 192.168.1.102 (format gsm)
    -- Format for call is gsm
    -- IAX2/alex-2 is ringing
    -- Nobody picked up in 5000 ms
    -- Hungup 'IAX2/alex-2'
    -- Executing [s at incoming:3] Hangup("Zap/4-1", "") in
new stack
    -- Hungup 'Zap/4-1'

At this point the caller (say, me on my cell phone) still 
sits connected and enjoying the white noise. The longest I
waited was about 20 seconds and then I hung up.

Similar problem is described here (November 2006) -

but there's no solution and the discussion is not very
helpful.

Any pointers and/or ideas are greatly appreciated.

Thanks,
Alex

That's ok, and is expected behaviour. The telco will keep the line
open for about 30 seconds. It's useful when there is no PBX, and just
2 or 3 phones attached to the same line... you can hangup on one room,
go to another, pickup and continue the conversation.

Anyway, i guess the telco can reduce that timeout or remove it
completely. Just tell them you have a PBX on that line.
