FXS port to Fax Server - Passing Digits

There are numerous posts on this setup with fairly inconsistent information. Everything I read says FXS can't send dialed digit outbound and that FXS/DID functionality is inbound to the port only.

FXS can't pass dialed digits (from Cisco):

I found this posting with someone running an FXS card that is successfully passing digits to a fax server:

I have a FaxFinder server with 2 FXO ports that is providing fax functional for ~20 users. I need to connect 2 FXS ports to this fax device and pass the dialed digits so the fax server can match the number with a fax email address.

Can anyone provide direction on whether this will work?

Thanks,

Joe

There is no inconsistency.

FXS cannot pass digits before stations answers.

It can pass digits after station answers.
