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

any 3G cell phone also supports fast Cellular Internet VoIP

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

(ITSP) place calls from home, office & public Wi-Fi hot-spots Receiving a

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

Corporate PBX WiFi Architecture Benefits Radiation is very low Allows free calls to the office

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

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

if the employee was sitting at his desk Employee s office telephony extension will follow him anywhere around the globe

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

calls can be routed to the cellular phone when the unit is out of the IP

22 ADDITIONAL WAYS TO OPTIMIZE CELLULAR COMMUNICATION

23 Wireless Connection for the ipbx 1. Many mobile providers supply unlimited high speed Cellular Internet (HSDPA) 2. 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 Internet Corporate Office IP-PBX WiFi Router WiFi HSDPA Modem IP-PBX LAN Analog Extensions GSM/WiFi Phone Extensions

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

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
