  • 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.
  • Transcript

    • 1. Reduce Communication Costs While Increasing Accessibility Fixed Mobile Convergence with an IP-PBX
    • 2. Agenda
      • Cellular Phone Connectivity Options
      • How an IP-PBX Improves the Equation
      • Application Scenarios
      • Case Study
      • Additional Ways to Utilize Cellular Communication
      • Summary of Key Points
    • 3. CELLULAR PHONE CONNECTIVITY OPTIONS
    • 4. Cell Phone Connectivity Options
      • Many cellular phones today are “dual mode”, supporting both GSM and Wi-Fi
      • In addition, any 3G cell phone also supports fast Cellular Internet
      • VoIP connectivity on these phones is enabled via a soft phone client
    • 5. Land Line Calls and Cell Phones
      • Originating a SIP call
        • Internet-enabled cell phone owner registers to an Internet Telephony Service Provider (ITSP)
        • place calls from home, office & public Wi-Fi hot-spots
      • Receiving a SIP call
        • feasible (with “follow me” for specified PSTN phone number), but not practical
    • 6. HOW AN IP-PBX IMPROVES THE EQUATION
    • 7. Cell Phone Usage Options
      • Standard Use Drawbacks
      • Indoor use produces excessive radiation
      • Cellular calls are generally much more expensive than land line calls
      • No direct access to Corporate PBX
      • WiFi Architecture Benefits
      • Radiation is very low
      • Allows free calls to the office and low cost external calls, even from places that charge excessive roaming fees
      • Direct access to Corporate PBX
    • 8. IP-PBX Supports VoIP Cell Phones
      • VoIP-enabled cellular phone registered on IP-PBX
        • No ITSP registration required
      • Calls to the employee’s extension will be forwarded to his cell and/or soft-phone
      • Call initiation and reception from cell phone as if the employee was sitting at his desk
      • Employee’s office telephony extension will follow him anywhere around the globe
        • full PBX/cellular services and flexibility
        • low office extension local telephony costs
        • low radiation levels for dual-mode phones
    • 9. New Ways SMBs Can Use Phones
      • Cell phone can be used as the phone extension in the office…and everywhere
      • Employees can be reached via a single number
        • incoming calls can be routed to the cellular phone when the unit is out of the IP network area
      • Install a soft phone on the laptop and receive calls on the computer as well
    • 10. APPLICATION SCENARIOS
    • 11. Sample Small Office Setup PSTN GSM/WiFi Phone Extensions IP-PBX Analog Extensions and/or VoIP Provider LAN WiFi WiFi Router
    • 12. Office Scenario LAN WiFi
    • 13. Home/Hotel Scenario Home/Hotel LAN and WiFi WAN
    • 14. Off-Premise WiFi Scenario Café LAN WiFi WAN
    • 15. Off-Premise Cellular Scenario Cellular Data Network Cellular Internet
    • 16. Larger Corporate Set-up PSTN GSM/WiFi Phone Extensions IP-PBX Analog Extensions and/or VoIP Provider LAN WiFi Channel Banks PRI/BRI/FXO
    • 17. BENEFITS RECAP
    • 18. Benefits of WiFi/Cell Architecture
      • Telecommunications costs are lowered without changing employee habits
        • calls from cell phones are routed to the PBX
      • Higher employee availability
        • extension rings cell when in WiFi/Cellular Internet range
      • Lower radiation for calls within WiFi range
        • no cellular transmission
      • Improved functionality
        • all PBX features (conference, recordings, etc.) available to cell phone
    • 19. CASE STUDY
    • 20.
      • Leading global provider of remote people monitoring technologies
      • Business and administrative presence in over 25 countries worldwide
      • Using two IP-PBX
        • one inside LAN
        • one in DMZ for cell phone users only
      • Serves home and mobile users
    • 21. Dmatek Telephony Architecture GSM/WiFi Extensions IP-PBX LAN WiFi/Cellular Internet WAN IP-PBX PRI LAN WiFi
    • 22. ADDITIONAL WAYS TO OPTIMIZE CELLULAR COMMUNICATION
    • 23. Wireless Connection for the iPBX
      • Many mobile providers supply unlimited high speed Cellular Internet (HSDPA)
      • When neither HSDPA nor wired infrastructure is available, GSM Gateways can be used to provide cellular-based PSTN access
    • 24. 3G Cellular Internet Option
      • When no wire infrastructure is available, IP-PBX connectivity can be achieved with the 3G Cellular Internet using the HSDPA modem
      • Cellular Internet Access Package typically costs less than cellular call rates

    • 25. GSM Gateway Option
      • Relevant in geographical areas where:
        • landline infrastructure is lacking
        • wired Internet is missing
        • HSDPA is not available
      • Routes incoming/outgoing cellular-targeted calls via the mobile telephone network, for low-cost mobile-to-mobile calls
    • 26. GSM Gwy + iPBX Network Schematic PRI Connection GSM Gateway IP-PBX Channel Banks Analog Phones SIP Phones Corporate LAN Cellular Telephony
    • 27. SUMMARY OF KEY POINTS
    • 28. IP-PBX: Greater Access, Lower Costs
      • Place/receive calls via cell/soft phone, no matter where located
      • Auto forward incoming calls to mobile user
      • Capitalize on WiFi access where available to save costs and minimize health hazard
      • Utilize Cellular Internet when WiFi is not available
      • HSDPA or GSM Gateway in landline-limited areas
      • Provide cell/soft phone users with full and direct access to IP-PBX functions
