Who is Using them

SIP trunks are rapidly replacing traditional analogue lines including BRI, PRI E1 around the globe, SIP trunks or Session Initiated Protocol trunks provide a much more flexible and and affordable alternative to previous outdated technology.

 Many European companies have already completely replaced their ISDN network with SIP trunks with the rest of Europe to follow shortly. Most business in North America have already switch to modern VoIP enabled telephones and are using sip trunks to power their organization. The cost and flexibility of SIP trunks have been the driving force behind this transition. The SIP Trunking service is usually provided by an internet service provider (ISP) but unlike a PTSN provider, the lines provided are not physical lines, but a service provided over your internet connection. The SIP Trunk Provider provides phone numbers and lines, at better rates than the traditional providers and with more flexibility and shorter or no contract durations.



SIP Trunks

A SIP trunk basically provides the ability to pass voice calls over the internet, your Internet Telephone Service Provider provides you with the number of channels or concurrent calls required for your business. The ability to control this from their network is what allows them to add or remove channels on demand and provides the flexablity and cost benefits for your business.  SIP trunks also provide the ablity to scale the number of channels required by your business at any given point, if you are a seasonal business your can lower the number of channels required in the off season and lower your monthly costs.
