Transcoding requires hardware DSPs.
Yes, I would recommend using a dedicated MRG/L for this hardware transcoder that is local to the Lync Mediation server.

For whatever reason, upper management likes Lync audio conferencing and wants to integrate it with Cisco.
Lync uses G711 between cisco and the Mediation server.
So I need to transcode at the site local to Lync from all other sites.
1. Could I use MTP (IOS software MTP) so I don't need to use DSP resources for the transcoder?
My intended design is this:
Remote sites Lync site
WAN Site 1 ----------
WAN Site 2 ----------
Create device pool/region for Lync
Create a dp/region for the transcoder/MTP
Set G711 between transcoder region and Lync region
Set g729 between all other regions and transcoder region
Put transcoder/MTP in each site MRG
Put ONLY this transcoder/MTP in the lync mrg
2. Would I also need to create a mrg to use for the transcode DP so it only uses this transcoder?
