What is required to convert a G711ulaw call to G729?

A.
Voice Termination resources

B.
Conferencing resources

C.
Converter resources

D.
Transcoding resources

Explanation:
Transcoding compresses and decompresses voice streams to match endpoint-device capabilities.
Transcoding is required when an incoming voice stream is digitized and compressed (by means of
a codec) to save bandwidth, and the local device does not support that type of compression -> D
is the correct answer.
