Refer to the exhibit. This INVITE is sent to an endpoint that only supports G.729. What must be done for this call to succeed?
The correct answer is B. Add a transcoder that supports G.711ualw and G.729. A transcoder takes the media stream of one codec and transcodes (converts) it from one compression type to another compression type. For example, it could take a stream from a G.711 codec and transcode (convert) it in real time to a G.729 stream. In addition to codec…

Explanation
A transcoder takes the media stream of one codec and transcodes (converts) it from one compression type to another compression type. For example, it could take a stream from a G.711 codec and transcode (convert) it in real time to a G.729 stream. In addition to codec conversion, a transcoder resource can also provide MTP/TRP functionality to a call.
