SIP trunks


At long last SIP trunks are well and truly here and revolutionising the way that businesses work, offering businesses of all sizes flexibility, performance, service options and most importantly of all, excellent savings.

A SIP trunk is a direct connection between your business and an Internet Telephony Service Provider (ITSP). It enables you to extend voice over IP (VoIP) telephony beyond your firewall without the need for an IP-PSTN gateway. This simpler configuration is easier and less expensive to design, operate, maintain, and upgrade.
