AT+CLIP - Calling line identification presentation

This command refers to the GSM supplementary service CLIP (Calling Line Identifica-
tion Presentation) that enables a called subscriber to get the calling line identity (CLI)
when receiving a call.
The set command + CMP=<n> enables or disables the presentation of the CLI at the
M1. It has no effect on the execution of the service CLIP in the network. When enabled
+CLIP: <number>,<type> response is returned after every RING result code.
The read command +CLIP? gives the status of mode n and also triggers an interroga-
tion of the provision status of CLIP in the network.
