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

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

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
low radiation levels for dual-mode phones

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

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

ADDITIONAL WAYS TO OPTIMIZE
CELLULAR COMMUNICATION
www.xorcom.com
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
www.xorcom.com
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
