"You are not tied to your computer. You can make VOIP calls when and where you want. Our service is also good for travelling - unlike other VOIP options Mint allows users to call from other countries - as they travel globally and still receive cost savings."

Jepson said Mint Telecom will be able to operate more cheaply in Australia than other VOIP providers (such as Skype), because, by making ordinary PSTN calls from Mint Telecom servers, the company boycotts any broadband charges.

All that is needed for the service to work in Australia are DIDs, which Mint Telecom plans to make available in Q2 and then globally in Q3.

"We have several key relationships with DID vendors in North America and globally. We are in process of beta testing new regions for call quality and termination quality," Jepson said.

"We are a SIP-based, back-end software service that integrates easily into any system, so any company in the world could use and offer our service."
