Say you have DP-Phone, which has MRGL-Phone assigned to it at the DP level,. This is assigned to the phone. This MRGL does not have a transcoder
You also have DP-Gateway, which has MRGL-Gateway assigned to it at the DP level. This is assigned to the gateway. This MRGL does have a transcoder
If you were to place a call which used the G.729 codec (and needed to be transcoded), I would expect the transcoder to be invoked since it's in the MRGL of the last hop. But if the transcoder was only in the MRGL of DP-Phone, would it be invoked?
Basically what I'm asking here is if multiple MRGL's are concatenated, or only the last MRGL is used.
