Enable your employees call each other for free with OfficeSIP Server. Multi-office and trans-national corporations pay thousands of dollars for long-distance calls every month even after considerate savings made possible with IP telephony. Voice over IP is great for saving money on long-distance calls, so why not to make the next step? Enable employees call each other for absolutely free no matter where they are in the world. With OfficeSIP Server you'll be able to use regular telephones, including wireless handsets or headsets, and will never pay a penny for long-distance calls.
