There are numerous VoIP or Voice over Internet Protocol systems surfacing these days and fast gaining ground on traditional mobile and land-line providers. One of the up and coming systems is Asterisk (although it has been in development for 10 years). Asterisk is a software version of a PBX and like all PBX systems, users can call each other and users of any of the other connected networks such as PSTN and more recently VoIP. Asterisk due to its open source / GPL core has many features and is continuously in development worldwide. There are a large number of providers and supporters of the Asterisk software due to its popularity. Asterisk Phone Systems Toronto offer full support of this service enabling traditional analog telephones to connect to an Asterisk installation as well as the fast emerging VoIP networks.
Of course, there are numerous providers of VoIP services around the globe. The VoIP technology coupled with the fast increasing usage of the Internet in general has added to its rapid growth, mainly due to the ability to connect to existing PBX systems and offer calls at a much lower rate than the traditional mobile / land-line providers. Skype and Vonage are good examples of this and their usage figures are increasing by the minute, purely due to the cost savings involved.
