Voice over Internet Protocol (Voice over IP, VoIP and IP telephony) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).

As well as the traditional range of Analogue ISDN2 and ISDN30 services, gig06 also provides a comprehensive range of VoIP services based on SIP. Not only do these services offer far more attractive line rental and call charges, they also offer significantly more flexibility over the non-IP services. For example, DDI ranges can be split over multiple locations, geographic numbers can be routed and terminated into any location and many inter-network calls can be delivered effectively on-Net and as such, at no call charge. And what is more, even if you are using TDM-based office telephony, you are able to take advantage of our VoIP services through a gig06 provided adapter.
