Which codec complexity type will offer the greatest number of voice channels, provided that the
complexity type is compatible with the particular codecs that are in use?

A.
low complexity

B.
medium complexity

C.
high complexity

D.
flex complexity

Explanation:
Codec complexity refers to the amount of processing required to perform voice
compression. Codec complexity affects the call density—the number of calls reconciled on the
DSPs. With higher codec complexity, fewer calls can be handled. Select a higher codec
complexity if that is required to support a particular codec or combination of codecs. Select a lower

codec complexity to support the greatest number of voice channels, provided that the lower
complexity is compatible with the particular codecs in use.
