Summary:                    [patch] Aborted inbound trunk call to FXO analog
port causes internal extensions (SIP or DAHDI) to ring forever.
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.

ARRAYLEN(ringdata) before call to my_distinctive_ring=3, but inside
my_distincetive_ring=1, so have hardcoded 3. (must be a better way!)

if dringXcontext=internalX wasn't set, the dial plan would wipe out
default context.
core show channels, after first call had an empty defcontext.

print 'Detected ring pattern, 300,200,100' to aid in distinctive ring
setup.


/etc/asterisk/chan_dahdi.conf
...
;usedistinctiveringdetection=yes
;
; enable dring detection after caller ID for those countries like
Australia
; where the ring cadence is changed *after* the caller ID spill:
;
distinctiveringaftercid=yes
;
; Whether or not to use caller ID:
;
usecallerid=yes
