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

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

HOW AN IP-PBX

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

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

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

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

 one inside LAN

 one in DMZ for cell phone users only

ADDITIONAL WAYS TO OPTIMIZE

CELLULAR COMMUNICATION

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

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

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

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
