asterisk users - Oct 2006 - MODEM (data) througt asterisk ?

Hi all,

Is it possible to connect a modem to a remote service through asterisk ?
Basicly to ilustrate : Accounting department need to connect with analog 
modem to their bank to order some wire transfert.

Modem <-> Chanel Bank FXS <-> Asterisk <-> TDM2400 FXO
<-> Modem in
remote site.

Actulaly, the modem dial, wait and disconnect after 1-2 minutes because 
It couldn't connect.

Any sugestion ?

Thank you in advance.
Florent.

It's only *remotely* possible if everything's G.711 all the way
through, I think.  If there are any analog transitions in the middle
(and possibly even if there aren't) you won't get anything over
33k6bps, and probably less than that.

*Any* phase non-coherence will break anything faster than 202/212, I'm
pretty sure.

Cheers,

If you get it working you're lucky. Digium's official statement on the
TDM2400 is "that card as been designed for voice calls, we don't
support data calls"

You would have better luck with a Sangoma A200
