In CP, how to

handle low

bandwidth

calls

If a Continuous Presence call tries to connect using a

lower bandwidth than defined by this service, the VCB

will handle the call’s bandwidth according to the selected

setting.

Do nothing

- This setting is not applied to calls.

Reject the call

- The VCB does not allow the call to

continue.

Open only audio

- The VCB allows the audio stream

to continue.

Use Speed Matching

- The call continues at [4x the

VCB Service's defined bandwidth + 64 Kbps audio].

However, all end points not supporting this

bandwidth receive the call at the lowest bandwidth

used among all participants.

The table below shows the bandwidth used when a

Continuous Presence call of [320 x4 Kbps + 64 Kbps

audio] connects, resulting in the transfer of the full

1.5 Mbps bandwidth to those end points supporting

it, but all end points supporting less (than 1.5 Mbps)

bandwidth only receive 128 kbps.
