+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, 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 can have only one call on hold at a time.
Note:
December 31, 2007
Only voice calls can be put on HOLD.
A precondition for the multi-party service is that the G24 is in control of one active call
and one call on hold. In this situation, the G24 can request the network to begin the MTPY
(Multi Party) service. Once a MTPY call is active, remote parties may be added,
