— automatic number identification — a device that supports a similar feature requests the number of the caller from the PBX and displays it on the phone display. The Caller ID standard is supported by the majority of PBX. But here it is important to understand that when a caller's number is requested, a connection is immediately established and, regardless of whether the person at the other end picks up the phone or not, it is from this moment that the call is billed.
