What Is An IP Phone System?
At the heart of every business phone system is the PBX (Private Branch Exchange), which makes connections among the internal telephones of a business or other private organization and connect them to the public switched telephone network (PSTN). Traditional hard-wired PBX systems evolved in the 1990s to use Internet Protocol (IP) to carry calls. An IP PBX uses Voice Over Internet Protocol (VoIP) and can also be known as a VoIP PBX, IP-PBX, virtual PBX or IPBX.
IP PBX phone systems perform four main call processing duties:
- Establishing connections between the telephone sets of two users
- Maintaining the connections as long as needed
- Disconnecting the connections when the users hang up
- Providing information for accounting purposes
An IP PBX system consists VoIP enabled phones and an IP PBX. The phones register with the IP PBX server, and when they make a call the IP PBX establishes the connection. VoIP phones can be simple software-based softphones or purpose-built hardware devices that appear much like an ordinary telephone or a cordless phone.
ShoreTel integrates communication features such as video conferencing, instant messaging (IM), mobility and online collaboration into a single easy-to-use IP PBX solution. Eliminating separate tools is only one way that ShoreTel's brilliantly simple VoIP phone systems help boost productivity and reduce costs.
ShoreTel For Managed Cloud Phone Systems

Most hosted cloud business phone service providers utilize core technology that is developed and maintained by a third party. But ShoreTel is an "end-to-end" provider, from the phones to the platform to the applications software—so of course we built our own hosted platform in the cloud. Our cloud phone system is the key to our solution and is engineered for highest reliability and functionality.
Our technology tailors the user experience for companies who put a premium on sales and service and consider the phone to be a strategic part of their business. It allows us to integrate more tightly with other business applications and to have granular data measuring everything we manage.
ShoreTel For Onsite Business Phone Systems
Built to leverage the power of VoIP telephony, ShoreTel IP phone systems have pioneered a fundamentally different approach to IP PBX. Thanks to its ingenious purpose-built single-image architecture, a ShoreTel on-premises communications platform grows across as many sites, or as many continents, as you need. IT staff can manage your entire VoIP phone system with plug-and-play ease using a single browser-based interface. And because it is an open system, it integrates with popular business applications, enabling you to get more out of your most valuable assets: people and information.
The ShoreTel distributed architecture is incorporated into a unique on-site, appliance-based, IP PBX platform with no single point of failure: each switch and site functions as an independent call processor. In the event of wide area network (WAN) failure, the phone system continues to place and receive calls on the Public Switched Telephone Network (PSTN). This gives customers 99.999% availability for 100% peace of mind.
ShoreTel's on-premises IP PBX phone system offers the lowest TCO in the industry. Many customers report a return of investment within a year. Over the long term, the unified communications tools of a ShoreTel business VoIP telephone system reduce costs company-wide by streamlining business processes, putting critical information in reach, and eliminating both missed calls and the need for expensive third-party conference services.
