A 1300 or 1800 number gives a business a single, memorable number to put on marketing, signage, and invoices, regardless of how many physical sites or staff sit behind it. A 1300 number is charged to the caller at a standard local-call rate; an 1800 number is free for the caller, with the cost carried by the business instead.
Both number types support flexible call routing – ring a group all at once, ring in a set order, or route differently depending on the time of day or the caller’s region – and can be layered on top of an existing phone system without new hardware.
