11.13 AT+COLP Connected Line Identification Presentation
This command refers to the GSM/UMTS supplementary service COLP
(Connected Line Identification Presentation) that enables a calling
subscriber to get the connected line identity (COL) of the called party
after setting up a mobile originated call. The command enables or
disables the presentation of the COL at the TE. It has no effect on the
execution of the supplementary service COLR in the network.
When enabled (and allowed by the called subscriber), +COLP:
<number>,<type>[,<subaddr>,<satype> [,<alpha>]] intermediate
result code is returned from the TA to the TE before any +CR or V.25ter
responses. It is manufacturer specific if this response is used when
normal voice call is established.
Read command gives the status of <n>, and also triggers an
interrogation of the provision status of the COLP service according
3GPP TS 22.081 (given in <m>).
Test command returns values supported by the TA as a compound
value.
