SIP Trunks

SIP trunks are an efficient way to use your internet connection for voice calls through an on-site telephone system as opposed to traditional analogue or ISDN lines.

As the monthly rental for a SIP trunk is much lower than an ISDN channel, real cost-savings can be achieved. Each SIP trunk represents the capacity to make or receive a call, meaning faster provision and scalability - depending on a business's needs.
