Summary:                    Aborted trunk call into FXO keeps destination FXS
port ringing
Description: 
Confirmed with a TDM800P with 1x 1port FX0 module and 1x 4port FXS module.

The only way to stop the ringing extension, was to pick it up.

The senario was:
  FX0 connected to outside line.
  FXS connected to analog phone.
  ring home line (from cellphone).
  wait for internal FXS connected phone to ring 1 or 2 rings. Hangup call
from mobile. 
  FXS connected phone keeps ringing forever.
  To stop the ringing, pickup ringing handset.

Deployed 1.6.1.0 branch, with same configs, no problems now.

---------------------------------------------------------------------- 
DAHDI SVN version 6675.
Debian Lenny.

I also noted that asterisk console appeared to lock (not segfault) after
'channel request hangup' was tried, to determined wheter the lines had
indeed been hungup.

Also noted with asterisk SVN, I had dialled an external number, then
transferred to another extension, that transfer went ok.
Minutes later when I came back to the orignal extension that I had
initated the tansfer from, that the dialtone was ring tone, every time I
picked up the handset. Only fix was restart asterisk, which wouldn't die,
had to use kill -9...

This makes me wonder wheter asterisk had 'hung' tight, with the constantly
ringing bell on reported extension. But in the background DAHDI was happy
to remove Bell generation when it saw the offhook.
