RE: Re: Comfort & Asterisk

["Graham Kiff" <graham.kiff@xxxxxxxxxxxxx>]

I'm using a TDM400

I've tried listening in parallel and it sounds to me as if comfort is
not recognising the off-hook state when asterisk dials.  When I listen
to the line with a regular phone after approx 4 secs I hear a very
slight tone change in the dial tone - this would suggest it's changing
from the comfort generated dial tone to the BT PSTN dial tone.

However when I perform the say test via asterisk, I hear a dial tone,
but no change after 4 secs.  If I dial *xxxx# I hear a "BT
voice", so
this dial tone is PSTN generated.  I first thought that asterisk was
ignoring the comfort generated dial tone, but this cannot be the case as
I only wait approx 1-2 secs before hearing the BT dial tone via
asterisk.  I'm really confused!!!!

Which FXO? An X100p or a TDM400?

Have you tried creating an extension which dials the FXO with your
comfort access string explicitly on your behalf. This might solve the
timing issue? It would also be worth listening in parallel with the
exchange line when you dial to ensure that the "*" is actually
being
passed as DTMF.
