A voice engineer is trying to configure CUCM to satisfy the following customer codec requirements.
-All IP phones should use audio codec at less than 10K bandwidth and maintain voice quality
-The IP phone audio codec selected should be optimized for speech and music
-The audio codec should be used in outbound SIP early offer signalling
Which configuration best satisfy the requirement?
A.
B.
C.
D.
AAC-LD can also process stereo signals by using the advanced stereo coding tools of AAC. Thus it is possible to transmit a stereo signal with a bandwidth of 7 kHz
I believe this is Correct.
I can’t find any documentation supporting the bandwidth for AAC-LD being < 10kbps. Can anyone assist?
