[Ken Rice]

again there is no bypass or proxy media for TDM. bypass media does only works with sofia it is a special mode. proxy media is also only for sofia.

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?

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.
