+CHLD, Call Related Supplementary Services Command

This command controls the Call Hold and Multiparty Conversation services. This command manipulates voice calls only.

Set Command

The Set command allows the control of the following call related services:

•Call HOLD: A call can be temporarily disconnected from the G24-L, but the connection is retained by the network.

•MTPY (Multi party) Conversation: Conference calls.

The network does not reserve more than one traffic channel for a mobile station, therefore the G24-L can have only one call on hold at a time.
