If you're on the hunt for business phone service that is reliable and budget-friendly, Voice over Internet Protocol (VoIP) is your answer.

Today's small-to-medium-sized (SMB) businesses and large enterprises are saving on their monthly communications costs by making one simple decision: to switch to a VoIP service solution from their old, outdated Plain Old Telephone Service (POTS). By choosing a new VoIP service, these companies enjoy the flexibility, reliability, call features, and audio quality that only a VoIP service can provide. Plus, they cut their phone bill by up to 70%!

  • I honeslty think this program the best program I at all times used! => consider having a look at this webiste for Free Gift Cards :

  • This little miracle works as charm. Does exactly one thing and it does it good: it causes 100% load on all (or selected) CPU cores. It also manages to use plenty of RAM, so it does check your system stability well. BTW, it also calculates PI decimal digits which is also totally awesome for any nerd :) Although I don't speak C++, I've seen the code and it's readable even for such ignorant as myself ;) I learned a lot about calculation algorithms from the sources and was even able to implement them myself in my C# code. The program was a godsend when I played with overclocking my PC. If any setting was suboptimal - System Stability Tester caused BSOD-s and restarts. Without it it would probably take days to find out if the new overclocking settings are OK.

  • A great option for testing the system!

  • Really great work. I love this software. New wiki in the making too, so should be easier for new users to get going. Give it a try, you won't regret it :)

  • Great job! Light weight and fast to boot.
