[cisco-voip] Device > Gateway > H323 > Checking Media Termination Point Required and Enable Inbound FastStart

[Ryan Ratliff]

Inbound FastStart support does not require MTP, only outbound.  

Other than that MTPs don't transcode, transcoders so.  As Nicholas pointed out software MTPs only support one codec (the IOS ones can be configured to use various codecs, the CUCM software MTPs only support g.711).

Most people use g.729 IOS software transcoders when they have a trunk that requires early media (either via SIP or H.323 faststart) with g.729 as a transcoder won't support a non-g.711 call leg.

Anyone disagree with me that best practice says you don’t use G729 as default codec and have CallManager doing Software MTP transcoding from G729 to G711 and vice
 
If you want transcoding you really should do it in hardware, eh? 
 
I’m trying to figure out if someone knew what they were doing and wanted to force software transcoding at this customer…or didn’t really know what they were doing.
