AT+CLIR=[<n>]
Set command overrides the CLIR subscription when temporary mode is
provisioned as a default adjustment for all following outgoing calls. This
adjustment can be revoked by using the opposite command. This
command refers to CLIR service (see 3GPP TS 22.081), that allows a
calling subscriber to enable or disable the presentation of the Calling Line
Identification (CLI, i.e., the phone number of the caller) to the called party
when originating a call.
This command sets the default behavior of the device in all outgoing calls.
