Sony Ericsson GM48, GM47 manual Integer type equals to numbers entered before Send

GM47/GM48 INTEGRATOR’S MANUAL

It is recommended (although optional) that test command returns a list of operations which are supported. The call number required by some operations is denoted by “x” (e.g. +CHLD: (0,0x,1,1x,2,2x,3)).

<n>	Description
...	Integer type; equals to numbers entered before SEND
	button in GSM 02.30 subclause 4.5.5.1
0	Releases all held calls or sets User Determined User Busy
	(UDUB) for a waiting call
0X	Releases a specific call X from a held multiparty call
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 is supported
3	Adds a held call to the conversation
4	Connects the two calls and disconnects the subscriber
	from both calls (explicit call transfer)

“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. Where both a held and a waiting call exists, the above procedures shall apply to the waiting call (i.e. not to the held call) in conflicting situation.

Note! The “directory number” case shall be handled with dial command D, and the END case with hangup command H (or +CHUP).
