How SIP Trunks work
SIP trunks are digital VoIP “lines” that significantly reduce call charges for businesses of any size whilst allowing complex routing options to maximise the efficiency of your phone system. For example, a US-based company might add some of our SIP trunk channels to their PBX to route all UK-bound calls through. Adding a SIP trunk route to your existing cloud-based or inhouse PBX system is really easy within your software (eg 3CX or Asterix).
International SIP
Our SIP trunks are extremely popular for international companies who need high quality and low cost VoIP call routing for UK-based customers and branch offices. With low or no call charges and the ability to work with any PBX platform – all we need is an IP to confirm the SIP routing on our platform – businesses all over the World can enjoy trouble-free VoIP calls to the UK, including UK mobiles. Perfect for any size business or call center.
Reduced costs with SIP and VoIP
VoIP is inherently cheaper than full PSTN or ISDN call routing. With WebMate’s SIP Trunks, we bring those cost savings even further with FREE UK (01,02,03) and UK Mobile (07) call charges included with every SIP trunk channel and some of the lowest international outbound charges in the industry through our extensive network partnerships with telco’s and other VoIP providers in every country.
