> I am running Asterisk 1.6.2.17.2 with a Openvox A400 card with 2FXO/2FXS
> modules. I'm trying to set-up things to route analog fax calls from a FXO

>
> Outgoing faxes work just fine. But incoming faces are routed to the right
> DAHDI extension, but the call dropped right as the fax machine rings for
> the first time. The fax machine works fine when connected directly to the
> analog telephone line and I see the same behavior if I route the fax call to
> anyother DAHDI or SIP extension.
