  • An organization with ADSL Internet access and a Wi-Fi router. The IP-PBX is connected to the LAN. Cellular phones in the organization register to the IP-PBX.
  • At a hotel that has a wired LAN connection. Extension is now forwarded to the laptop.
  • At a cafe. Phone call received via Wi-Fi to cell phone (the call was forwarded by the secretary to the office extension). Calls to the office are free calls and land-line calls to other phone numbers charged as if from the office.
  • Out on the street. A call dialed to an office extension is routed by the IP-PBX, which determines that the cell phone is not currently registered as a SIP phone, to the cell phone using the cellular network.

    1. 1. Reduce Communication Costs While Increasing Accessibility Fixed Mobile Convergence with an IP-PBX
    2. 2. Agenda <ul><li>Cellular Phone Connectivity Options </li></ul><ul><li>How an IP-PBX Improves the Equation </li></ul><ul><li>Application Scenarios </li></ul><ul><li>Case Study </li></ul><ul><li>Additional Ways to Utilize Cellular Communication </li></ul><ul><li>Summary of Key Points </li></ul>
    3. 3. CELLULAR PHONE CONNECTIVITY OPTIONS
    4. 4. Cell Phone Connectivity Options <ul><li>Many cellular phones today are “dual mode”, supporting both GSM and Wi-Fi </li></ul><ul><li>In addition, any 3G cell phone also supports fast Cellular Internet </li></ul><ul><li>VoIP connectivity on these phones is enabled via a soft phone client </li></ul>
    5. 5. Land Line Calls and Cell Phones <ul><li>Originating a SIP call </li></ul><ul><ul><li>Internet-enabled cell phone owner registers to an Internet Telephony Service Provider (ITSP) </li></ul></ul><ul><ul><li>place calls from home, office & public Wi-Fi hot-spots </li></ul></ul><ul><li>Receiving a SIP call </li></ul><ul><ul><li>feasible (with “follow me” for specified PSTN phone number), but not practical </li></ul></ul>
    6. 6. HOW AN IP-PBX IMPROVES THE EQUATION
    7. 7. Cell Phone Usage Options <ul><li>Standard Use Drawbacks </li></ul><ul><li>Indoor use produces excessive radiation </li></ul><ul><li>Cellular calls are generally much more expensive than land line calls </li></ul><ul><li>No direct access to Corporate PBX </li></ul><ul><li>WiFi Architecture Benefits </li></ul><ul><li>Radiation is very low </li></ul><ul><li>Allows free calls to the office and low cost external calls, even from places that charge excessive roaming fees </li></ul><ul><li>Direct access to Corporate PBX </li></ul>
    8. 8. IP-PBX Supports VoIP Cell Phones <ul><li>VoIP-enabled cellular phone registered on IP-PBX </li></ul><ul><ul><li>No ITSP registration required </li></ul></ul><ul><li>Calls to the employee’s extension will be forwarded to his cell and/or soft-phone </li></ul><ul><li>Call initiation and reception from cell phone as if the employee was sitting at his desk </li></ul><ul><li>Employee’s office telephony extension will follow him anywhere around the globe </li></ul><ul><ul><li>full PBX/cellular services and flexibility </li></ul></ul><ul><ul><li>low office extension local telephony costs </li></ul></ul><ul><ul><li>low radiation levels for dual-mode phones </li></ul></ul>
    9. 9. New Ways SMBs Can Use Phones <ul><li>Cell phone can be used as the phone extension in the office…and everywhere </li></ul><ul><li>Employees can be reached via a single number </li></ul><ul><ul><li>incoming calls can be routed to the cellular phone when the unit is out of the IP network area </li></ul></ul><ul><li>Install a soft phone on the laptop and receive calls on the computer as well </li></ul>

    17. 17. BENEFITS RECAP
    18. 18. Benefits of WiFi/Cell Architecture <ul><li>Telecommunications costs are lowered without changing employee habits </li></ul><ul><ul><li>calls from cell phones are routed to the PBX </li></ul></ul><ul><li>Higher employee availability </li></ul><ul><ul><li>extension rings cell when in WiFi/Cellular Internet range </li></ul></ul><ul><li>Lower radiation for calls within WiFi range </li></ul><ul><ul><li>no cellular transmission </li></ul></ul><ul><li>Improved functionality </li></ul><ul><ul><li>all PBX features (conference, recordings, etc.) available to cell phone </li></ul></ul>
    19. 19. CASE STUDY
    20. 20. <ul><li>Leading global provider of remote people monitoring technologies </li></ul><ul><li>Business and administrative presence in over 25 countries worldwide </li></ul><ul><li>Using two IP-PBX </li></ul><ul><ul><li>one inside LAN </li></ul></ul><ul><ul><li>one in DMZ for cell phone users only </li></ul></ul><ul><li>Serves home and mobile users </li></ul>

    22. 22. ADDITIONAL WAYS TO OPTIMIZE CELLULAR COMMUNICATION
    23. 23. Wireless Connection for the iPBX <ul><li>Many mobile providers supply unlimited high speed Cellular Internet (HSDPA) </li></ul><ul><li>When neither HSDPA nor wired infrastructure is available, GSM Gateways can be used to provide cellular-based PSTN access </li></ul>
    24. 24. 3G Cellular Internet Option <ul><li>When no wire infrastructure is available, IP-PBX connectivity can be achieved with the 3G Cellular Internet using the HSDPA modem </li></ul><ul><li>Cellular Internet Access Package typically costs less than cellular call rates </li></ul>GSM/WiFi Phone Extensions IP-PBX Analog Extensions LAN WiFi WiFi Router HSDPA Modem Internet IP-PBX
    25. 25. GSM Gateway Option <ul><li>Relevant in geographical areas where: </li></ul><ul><ul><li>landline infrastructure is lacking </li></ul></ul><ul><ul><li>wired Internet is missing </li></ul></ul><ul><ul><li>HSDPA is not available </li></ul></ul><ul><li>Routes incoming/outgoing cellular-targeted calls via the mobile telephone network, for low-cost mobile-to-mobile calls </li></ul>

    27. 27. SUMMARY OF KEY POINTS
    28. 28. IP-PBX: Greater Access, Lower Costs <ul><li>Place/receive calls via cell/soft phone, no matter where located </li></ul><ul><li>Auto forward incoming calls to mobile user </li></ul><ul><li>Capitalize on WiFi access where available to save costs and minimize health hazard </li></ul><ul><li>Utilize Cellular Internet when WiFi is not available </li></ul><ul><li>HSDPA or GSM Gateway in landline-limited areas </li></ul><ul><li>Provide cell/soft phone users with full and direct access to IP-PBX functions </li></ul>
