 The Wilson Electronics Desktop (DT) cell phone signal Booster. View larger. |
It’s All About Power
The primary cause of dropped calls is low signal output power from the cell phone to the cell tower, which limits the phone’s ability to communicate with the tower. A typical cell phone provides merely one-fifth of a watt of output power. To address this problem, the amplifier and the outside antenna work together to increase the phone’s output power by more than 15 times over using just the phone alone.
Enjoy Premium Reception and Fewer Dropped Calls
If you have to go to the window or outside to be able to use your cell phone, you know the frustration of weak cell phone signal reception. Using state-of-the-art technology, the Wilson DT amplifies the signal both to and from the cell tower, increasing the power to penetrate through natural or man-made obstructions, thus enabling you to communicate where you were unable to before.
The Wilson DT comes with a compact signal booster that fits neatly on your desk or small table, and it works best when placed in the room where you’re experiencing problems with reception.
Included Hardware for Multiple Mounting Options
The Wilson DT is connected via a coaxial cable to the outside antenna, which performs best when mounted outside of the building and pointed towards the nearest cell tower. The antenna may also be mounted on a window (again, best when aimed at the nearest cell tower), or on an outside wall; however, some performance may be lost.
Once installed, the Wilson DT enhances the signal of multiple cell phones and data cards near the device. The result is that you will experience fewer dropped calls, clearer call quality, and improved data rates–even with 3G technologies.
Compatible with Most Cell Phone Models and Providers
The Wilson DT is compatible with all US and Canadian cellular providers, excluding iDEN, Nextel, and MIKE. Also, it supports CDMA, TDMA, GSM, and AMPS cell phone technologies, as well as data protocols such as GPRS, 1xRTT, HSDPA, EVDO, and EDGE. The use of radio distribution equipment that enhances, extends or amplifies a wireless signal may be prohibited without the consent of the wireless carrier upon whose network such equipment will be used. You should consult with your carrier before purchasing such equipment to use with that carrier’s service.
The Wilson DT Signal Booster includes a 30-day money-back guarantee and is backed by a one-year manufacturer’s warranty.

Q&A: What is the best software for recording calls made with VoIP phones in an office?
Question by admodieus: What is the best software for recording calls made with VoIP phones in an office?
We have come across a situation where we would like to record some phone calls made in the workplace through our soft VoIP phones. Optimally, this software would be able to run on a computer connected to the same network without having to install anything on the server – however, I am not opposed to any solutions including the server.
Best answer:
Answer by bully
What solutions are you running for VoIP in the office?
Do you use a voice gateway? Is there a PBX server for your VoIP solution?
Additional – There are numerous suppliers of call recording solutions. I would suggest contacting your VoIP provider re-seller and getting a quote from them.
All the solutions will require software running on a server and a connection to your network. Depending on the solution the recording will need to have multiple network connections, one for admin and playback and one that will most likely use port spanning to sniff for the rtp (voice packet data) streams in your network where that spanning occurs will depend again on what you want to achieve. To record external calls, the spanning can be carried out at the voice gateway but if you also wish to record internal calls then further spanning will be required.
Sorry I can’t be any more precise but without detailed knowledge of your network and VoIP solution I can’t offer any further advice.
