Who is it aimed at?

SIP trunks unlock the IP PBX and guarantee voice channels with the scalability required by any growing business. Our SIP offering is one of the first IP transit services in the market and gives flexibility to any business, small – medium – corporate. With a direct IP backbone reliability is comparable to digital BT circuits and SIP trunks can be used to replace or complement existing lines.

Many companies, recognising the flexibility and cost savings of SIP trunks are now using them as their primary source of communications with back-up ISDN and PSTN lines.
