Celerity Telecom’s PBX revolves around extensions and DIDs. Each extension is registered to a phone and you decide how you want the call to “flow” when someone dials your DIDs or TFNs.
Each DID can ring to an automated menu, a group of extensions, or other options. Each phone, while limited to one extension number per phone, can have multiple lines to receive multiple calls. International rates are available upon request.
