    8. 8. Hosted Voice-over-IP (VOIP) <ul><li>No on-premise phone system </li></ul><ul><li>Delivers service via digital circuits and network </li></ul><ul><li>Anticipated Life – 10, 20, 30 years? </li></ul><ul><li>Scalability – Limited by bandwidth </li></ul><ul><li>Associated Costs </li></ul><ul><ul><li>Phones; Possible cabling costs </li></ul></ul><ul><ul><li>Monthly cost of digital circuits </li></ul></ul><ul><ul><li>Fixed rates per phone </li></ul></ul><ul><ul><li>Low Maintenance / No Upgrade Costs </li></ul></ul>
    9. 9. Other Advantages of VOIP <ul><li>System can be accessed from the office, mobile phone, a “soft-phone” loaded on a computer, etc; Basically, any place with Internet access. </li></ul><ul><li>Calls can be routed from phone to phone or can ring all phones simultaneously; Establish your own routing rules </li></ul><ul><li>Business Continuity - If you lose your Internet connection for any reason, calls are automatically routed to voice mail </li></ul><ul><li>The system is administered via a web interface with minimal effort </li></ul><ul><li>Each user generally has their own direct phone number </li></ul><ul><li>Connect multiple offices on a single system </li></ul>

Common VOIP Concerns <ul><li>Can I keep my existing phone number? </li></ul><ul><li>Quality of service – The Vonage Experience </li></ul><ul><li>Reliability – What happens if I lose Internet? </li></ul><ul><li>What type of cabling do I need? </li></ul><ul><li>Can I use a fax machine with VOIP? </li></ul><ul><li>Can I page over VOIP? </li></ul>
    11. 11. Home Office Phone Options <ul><li>Consumer grade VOIP systems like Vonage, Google Voice or Skype </li></ul><ul><li>Virtual phone systems like My1Voice </li></ul><ul><li>Speakeasy Hosted Voice </li></ul>
    12. 12. Transitioning to VOIP <ul><li>Connect your existing phone system to an Integrated VOIP circuit </li></ul><ul><ul><li>Provides some of the cost savings of hosted VOIP </li></ul></ul><ul><ul><li>Provides some of the features of hosted VOIP </li></ul></ul><ul><ul><li>Easier to convert to a hosted solution when you are ready </li></ul></ul>
