Chances are that your business is already paying for an internet connection. Therefore you can now use a VoIP telecom solution to make calls at a much lower rate. A SIP trunk is the VoIP alternative of the conventional analogue, basic or primary rate telephone service. It caters for a single or multi-line environment and is used together with a Hosted Switchboard or a VoIP PBX. You can connect it to a traditional switchboard with a gateway telecom device.

You have a choice of a minimum of 4 up to 1000 channels. A channel determines the number of parallel telecom lines you can link to a number or numbers, to allow for concurrent calls both incoming and outgoing. This implies that a trunk is ideal for both small and large organisations, even call centres.
