What is an IP PBX Telephone System

An IP PBX or VOIP phone system replaces a traditional PBX or phone system and gives employees an extension number, the ability to conference, transfer and dial other colleagues. All calls are sent via data packets over a data network instead of the traditional phone network. With the use of a VOIP gateway, you can connect existing phone lines to the IP PBX and make and receive phone calls via a regular PSTN line. Calls can be diverted anywhere in the world because of the SIP protocol characteristics.

What are the benefits of an IP PBX?

• Much easier to install & configure than a proprietary phone system

• Easier to manage because of web based configuration interface

• No need for separate phone wiring

• Allows users to hot plug their phone anywhere in the office - users simply take their phone, plug it into the nearest Ethernet port and keep their existing number!

• Allows easy roaming - calls can be diverted anywhere in the world because of the SIP protocol characteristics

• Significant cost reduction by leveraging Internet

• SIP standard eliminates proprietary, expensive phones

• Scalable

• Better reporting

• Better overview of system status and calls

What is an SIP

SIP is the internet standard for real time voice and video communication. SIP (Session Initiation Protocol) was developed by the IETF and published as RFC 3261.

SIP is an internet protocol for live communications used in setting up and tearing down voice or video calls. It is a signalling protocol used to create, modify, and terminate sessions with one or more participants in an IP network. A session can be a straightforward two-way phone call or it can be a multi-media conference session with many persons participating. SIP has made possible an array of services that seemed unthinkable just a few years ago: internet conferencing, IP telephony, instant messaging, presence, voice and video communication, data collaboration, online gaming, application sharing, and much more.

SIP is doing for real-time communications what HTTP did for the web and SMTP for email. It is the main driver in the acceleration of the IP Telephony revolution. With SIP Telephony, a viable alternative to traditional PBX has emerged. SIP telephone systems deliver features that enhance users’ mobility and productivity, while securing substantial cost-saving advantages. This is making proprietary hardware based PBXs obsolete. Prices
