G.728Low-bit-rate codec that video endpoints support.It support kilobits per second.

In Cisco Unified Communications Manager (CUCM), the location bandwidth calculation is used to determine the amount of bandwidth required for voice and video calls between different locations in a network. The calculation takes into account the codecs used for the calls, as well as any other overhead or auxiliary traffic.

The G.728 codec is a low-bitrate codec that is typically used in low-bandwidth environments or for voice-only applications. It has a bitrate of 16 kilobits per second (kbps), which means that it can compress voice signals into a relatively small amount of data while still maintaining a reasonable level of quality.

To determine the amount of bandwidth required for a G.728 call in the location bandwidth calculation, we need to consider not just the codec bitrate, but also any additional overhead or auxiliary traffic that may be present. In general, the location bandwidth calculation assumes a certain amount of additional overhead for signaling, control, and other types of traffic that may be present in the network.

According to Cisco documentation, the default amount of overhead assumed for a G.728 call in the location bandwidth calculation is 16 kbps. This means that the total bandwidth required for a G.728 call is the sum of the codec bitrate (16 kbps) and the assumed overhead (also 16 kbps), which equals 32 kbps.

Therefore, the correct answer to the question is B. 16.
