It also means that you can use virtually any standards-based IP phone; Asterisk includes drivers for SIP and other protocols.

It wasn't long after administrators installed a PBX, they eyed features from the next generation of telecom hardware. Born out of frustration from replacing proprietary equipment, the hosted PBX rose in popularity. Call centers in the early s have pioneered today's PBX features such as headsets, softphone apps, and call routing. Innovations like these provided significant cost savings from analog phone systems.

IP PBX phone systems place and receive phone calls over the internet. It does so by converting analog voice signals into digital.

From there, it directs calls to a VoIP service provider to manage the initiation and termination of every call. This universal protocol has become the standard for VoIP phone systems.

Once authenticated, incoming calls are presented to your PBX to accept. Users can also reach an outside phone line by way of your SIP trunk automatically.

When a user places a call, the PBX server recognizes whether it's an internal or external call. Internal calls route to the SIP address of the phone or user receiving the call. External calls route to the VoIP gateway. The company may have its own VoIP gateway incorporated into the system, or use the gateway of a VoIP service provider.

The gateway device can take the form of a dedicated appliance, or as an expansion card in the server. Like other gateway devices, it has two or more ports to allow it to span multiple networks. Hosted IP PBX solutions are turnkey solutions that don't require organizations to have personnel on staff capable of managing the system. PBX systems support caller ID, three-way calling, call forwarding, voice mail, and similar features that business phone users take for granted.

The nice thing about IP-based systems is that users' voice mail messages can be forwarded to their e-mail inboxes, so they not only get instant notification that a call has come in, but can also play the messages from their computers or handheld devices.
