Shoretel Ip Phone Systems

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, IM, mobility and online collaborationinto 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.
