These Cellular Terminals allow Cell to Cell calls for In-Plan free calls,
(called Least Cost Routing) In the USA, For example, calling ATT to ATT or Verizon to Verizon. Outside the USA, where inbound cell calls are free, the savings is realized in the differential between Wire to Wire calls versus Wire (wall rj11) to Wireless.

In Mexico, the National Bank- Banco de Mexico- was using 7mm minutes a month to alert customers of overdrawn accounts and VISA bills overdue-calling people on their cell (from TelMex wired lines), & SMS to their cell. The price difference was 7 cents a minute ! The system paid for itself in 90 days.

When the Wire PBX (Toshiba, Iwatsu, Nortel, Siemens, Panasonic, Trillium, ATT/Lucent) in your closet is co-located (fancy word for 'installed next-to') with the Wireless Cellular Terminal (called a Fixed Wireless Terminal-FWT), you save BIG $. You still dial a call as before, with your same desk phone, but the switch knows when you dial out if the call is Cell or Wire, then routes appropriately.

A lot to say, a lot to explain, a lot to comprehend? Sure is, but we can do it many ways worldwide. Installation nightmare? Not a problem as we've been doing these for years. We are backed up by techs Worldwide. Our Cellular PBX Solutions have been sold, delivered & installed in over 20 U.S Embassies & Consulates worldwide.

The 2nd reason these are so hot? We are now at 5-billion Cell Lines and 1-billion Wire Lines worldwide. A Multi-line Cell terminal finally competes as a stand-alone PBX, all wireless.

3rd rationale? Emergency backup to downed Phone PBX. Floods, Fire, Hurricane, Earthquakes, Heaven forbid, and these terminals are instantly up and running, (assuming the cell towers are Solar powered). Somewhat the same, though not, for a Cellular GSM Alarm Backup

Perhaps one of the higher-priced options, but then "you get what you pay for". Many terminals "lock up" calls-not 2N. None have integration to Outlook for SMS (text message), or 'Ring-Forward' sending desk calls to your Cell, seamlessly, without alerting the inbound caller. And when connected to a Quintum Gateway (then to the ISP), creates seamless VoIP environment sending calls digitized, through the internet, to the other country /party. This is called an E1 PRI. 32 SIM (30 active) for 30-live calls. This category is known as "call termination". Some terminals have 1-2-3-4 SIM per Channel (to rotate time/day/carrier), 2N can do 6 or 8 SIM.


2N also have rate tables for Least Cost Routing, a remote control unit (RCU), and can be programmed to distinguish Portability numbers (when someone keeps their phone number but changes carrier). Understand? Come into the live chat or skype for more details.
