Understanding VoIP – a basic overview

Voice over IP is littered with terms and concepts that might lead to confusion. However, there’s only a handful of terms that a buyer really needs to know – read on for the four major IP telephony concepts.

VoIP

Voice over Internet Protocol. This is an umbrella term for any form of voice communications where voice is carried over any IP network. This could, for example, be over your internal office data network, or over the Internet.

 

IP PBX

Remarkably similar to a conventional PBX, an IP PBX sends voice over an IP network (ie. using VoIP) rather than the PSTN.

 

Hosted VoIP/IP PBX

 

Your broadband connection carries voice traffic alongside data traffic, and extra PBX functionality (for example, voicemail) is held externally by a third party.

 

SIP/IAX/VoIP trunks

Use your broadband connection to make calls, often reducing the cost. Can be used in conjunction with an IP PBX for the “best of both worlds” – high quality calls for every day use while using trunks to save on international call charges.
