Call Holding Services - +CHLD
+CHLD - Call Holding Services
Execution command controls the network call hold service. With this service it is
possible to disconnect temporarily a call and keep it suspended while it is retained
by the network, contemporary it is possible to connect another party or make a
multiparty connection.
Parameter:
<n>
0 - releases all held calls, or sets the UDUB (User Determined User Busy)
indication for a waiting call. (only from version D)
1 - releases all active calls (if any exist), and accepts the other (held or waiting)
call
1X - releases a specific active call X
2 - places all active calls (if any exist) on hold and accepts the other (held or
waiting) call.
2X - places all active calls on hold except call X with which communication shall
be supported (only from version D).
3 - adds an held call to the conversation
4 - connects the two calls and disconnects the subscriber from both calls (Explicit
Call Transfer (ECT))
Note: "X" is the numbering (starting with 1) of the call given by the sequence of
setting up or receiving the calls (active, held or waiting) as seen by the served
subscriber. Calls hold their number until they are released. New calls take the
lowest available number.
Note: where both a held and a waiting call exist, the above procedures apply to the
waiting call (i.e. not to the held call) in conflicting situation.
Test command returns the list of supported <n>s.
