I have a setup wherein I inserted FS in-between a PSTN exchange and a PABX linked via E1 R2.  My TDM card has dual E1 ports - port A is connected to the exchange and port B to the PABX.  If there's a call that pass-through FS (EXCH > PABX and vice-versa), I want incoming media from one port to immediately sent to the other port.  What mode should I set in the dialplan?  proxy_media or bypass_media?  I have read the Wiki on proxy_media. It's very clear to me re handling of TDM media.

Thanks in advance for the inputs.
