Caller ID is a telephone feature that displays a caller’s phone number on the recipient’s phone device before the call is answered.The phone number, location and associated billing or subscriber name is shown on the handset’s display or a separate caller ID box attached to the phone.

The CLID feature is particularly useful when screening known, unknown, or unwanted calls. Unwanted calls are effectively deterred with the use of caller ID, including obscene, harassing and threatening phone calls.

Sender ID is a telephone feature that displays a sender’s phone number on the recipient’s phone device when the text message is received.

SIP number (also referred to as international or virtual number) is a 15-digit endpoint identified by the 15-digit numbers starting from +883140.

They are not dedicated to a single country.

Virtual (international) numbers are treated by Apifonica REST API as conventional telephone numbers. These numbers have all the same properties as conventional phone numbers except for they use SIP protocol to connect.

The only important thing about virtual numbers is that virtual numbers cannot be called from fixed or mobile numbers.
