EXS API and SwitchKit API message

Description

Park Channel 0x00BF

This message is used to park one or both channels involved in a connection. This message disconnects two parties but does not tear down the connection.

To park only one channel, enter the channel to be parked as both Channel A and Channel B in the AIB. When a channel is parked, it is not associated with any other channel and silence is transmitted to it. The channel may be used in a subsequent connection or released.

When parking two channels, the host will receive a positive acknowledgment to this message for the first channel and a DS0 Status Change message with a channel status of "parked" for the second channel.
