VoIP stands for Voice over Internet Protocol and is a generic term like the word “digital”. Put simply; it is sending voice as data packets over a data link like a network or broadband. VoIP can represent many elements to a phone solution.

SIP is a type of VoIP technology that allows you to connect to a traditional, on-premises telephone system and benefit from the savings and flexibility that VoIP offers.

On-premises phone systems (also called pbx) are the traditional telephone systems where the main central control unit would sit somewhere on your premises. Ideally a comms room (but quite often a cupboard or in the back of reception). These phone systems can still benefit from the use of VoIP technology.

Hosted phone systems are where the central control unit is located off-site in “the cloud” and you only have the extensions (handsets) on your site.

Not presently but watch this space. We do offer specialised internet connections that make multi-media applications like Skype work brilliantly.
