asterisk users - Dec 2003 - Forwarding a call to another FXO port

Greetings,

I'm trying to setup an option in my greetingmenu that would allow the caller
to select this particular option for emergency calls.  That option would dial
out on an available PSTN line to a cell phone number.

Currently it is setup as such

exten => 9,1,Dial(Zap/g1/<CELLPHONENUMBER> where
<CELLPHONENUMBER> is the number it is calling out to.

When option 9 is selected, a horrible feedback noise is heard and caller cannot
hear anything else.  The cell phone that the call is going to does ring and can
be answered and hears the same noise.

Hardware on this is Asterisk Box -> T100P -> Adtran750
FXO channels are 1 and 2 set in group = 1
Both channels otherwise operate normally
echocancel = 64
echocancelwhenbridged = no

Any ideas?

Raymond McKay

I would change the option number to something else because 9 is often
picked up in another context as "9NXXNXXXXX" 

You might have to make a sub menu in order to get there, but try using
2-8 for the menu options.

Actually I don't use 9 for anything in any context.  For small dialplans I
find it more confusing for users to have to dial 9 for anything.

I don't think the problem is as much with the dialplan, though, as it is
with the bridging of the two FXO ports Zap/1+Zap/2.  When 9 is pressed by the
caller, the call is made out the available FXO port and the cell phone ends up
ringing.  The problem really is that once that connection is made, the only
audio that passes is a loud feedback type noise.

Aaah yes,

I experienced similar problems.  I had problems making calls to/from
calls through my cards.  I had to play with the echo cancellation to get
it to manageable levels.

If this is going to be more of a mainstay installation, I would highly
recommend that you get a T100P card and channelbank.  They work like
champs and I've had virtually no complaints from any of those installs
I've done.

There are some aggressive echo cancellation codecs that you are supposed
to be able to use, but I never tried them....I just threw money at that
particular problem to fix it.  LOL


Tim.

Thats actually what I'm using already.  I had some issues with the X100P and
SBC's lines so I put in a Adtran TA750 and a T100P a while back.  This is
the first time I have tried to do an FXO to FXO call though.  FXO to FXS and
vice versa are fine with no problems.
