+COLP, Connected Line Identification Presentation
This command relates to the GSM supplementary service called COLP (Connected Line
Identification Presentation), which enables a calling subscriber to obtain the connected line
identity (COL) of the called party after setting up a mobile-originated call with the G24. For
example, after setting up a mobile-originated call to one number that is forwarded to another
number, the calling party will see the number of that third party.
When this command is enabled (and the called subscriber permits it), the following intermediate
result code is returned:
+COLP: <number>,<type>[,<subaddr>,<satype>[,<alpha>]].
Note: This command is activated when COLP is supported by the network.
