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

[Nandy Dagondon]

Yes. The frames need to be copied from one port to the other. However, FS
can still snoop on the media like detecting DTMF like an incoming caller
responding to an auto-attendant/IVR.  Will using "bypass_media" parameter
on the dialplan, the frames will just go from one endpoint (TDM channel) to
the other endpoint (TDM channel on the other port) in like manner?  Or
there are TDM parameters I need to know?

This is easy to visualize in SIP because packets just pass through the
switches/routers - not through FS.

Appreciate for more additional info.
