About PBX (Multiple Extensions)

PBX stands for private branch exchange. It is basically a business phone system that allows for a network of phones to work together within an organization. PBX systems feature extensions for each phone in the organization, which allow you to have phones hooked up without additional phone lines.

Ninja Number's Multi Plan allows you to set up a number as a virtual PBX with unlimited extensions, each with the ability to set up voicemail and link additional phones.
