[Freeswitch-users] TDM-to-TDM Pass-through Media

[Nandy Dagondon]

Hi Raul,

I know because freetdm drivers run in the FS hardware.  So, frames always
passthrough the server.

I also notice these FreeTDM applications: enable_dtmf, disable_dtmf and
disable_ec.  Perhaps I can test them.

Tks,
/Nandy
