Which types of voice ports allow a small office to provide outbound DNIS and inbound DID?
A. FXS and FXO
B. FXO and E&M
C. FXS and FXS-DID
D. FXS and E&M
E. FXS-DID and FXO
Answer: E

In a voice gateway, the configured codec complexity of the DSPs on a voice card can be changed. What is the impact on the DSPs if high codec complexity is configured?
A. The codec complexity affects call density, which is the number of calls that are reconciled on the DSPs. This results in lower call density when high complexity is configured.
B. With higher codec complexity, more calls can be processed.
C. Lower codec complexity supports the fewest number of voice channels, provided that the lower complexity is compatible with the particular codecs that are in use.
D. The DSP will process codecs that support high complexity transparently and shift to flex mode for those codecs that are not high complexity.
Answer: A

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
Answer: A
