It's Easy

Just connect the QuadroE1/T1 to your E1/T1 trunk or to your PBX. In minutes, you are able to make voice over IP calls from your standard phones and receive IP calls from a local PSTN number. The voice quality produced by the Quadro's digital signal processor (DSP) will almost always be better than that of your current long distance company.

If the QuadroE1/T1 is communicating with another Quadro device or IP phone on the far end, the calls will be nearly free. If you connect to a VoIP service provider, you can make long distance calls to any phone number on the public phone network for pennies a minute.

It's Inexpensive

The purchase price of the Quadro is more than justified by the quantifiable long distance cost savings on calls made through the Quadro. You will realize a quick payback on your initial investment and enjoy recurring cost savings every time you use your Quadro. No obsolescence. No upgrades. No maintenance fees. No license fees.

And Revolutionary?
Absolutely!
Interfaces

The QuadroE1/T1 has one port for a E1/T1 phone trunk that allows up to 24 (T1) or 30 (E1) calls in parallel. This port may be connected to a PBX or directly to the local PSTN. An Ethernet 10/100BASE-T port connects the QuadroE1/T1 to your local area network and a 10BASE-T port connects to your wide area network (WAN). A FXS port is included to facilitate testing and setup.

The interfaces alone do not convey the power of the QuadroE1/T1 or the abundance of diverse missions it accomplishes.
It's Flexible

 The Quadro unites the cost-reducing benefits of IP telephony with the ubiquity of the PSTN, which opens many scenarios for free phone calls. Connect PBXs of geographically dispersed departments of a company wherever they are in the world over IP. Free calls between the departments can quickly increase communication and effectiveness.

Since the QuadroE1/T1 contains call routing information, employees who are out of the office can still be reached automatically. The world becomes your virtual office. In addition, a pair of QuadroE1/T1 units can be deployed to provide virtual local numbers to parties anywhere in the world. Communication has never been so flexible.
It's Secure

Like other Quadro devices, the QuadroE1/T1 is packed with an array of network security features including a stateful inspection firewall.
How does the Quadro do it?

Although using the QuadroE1/T1 is easy, it is built on a very sophisticated and complex system. Inside the QuadroE1/T1 device, two communications infra-structures come together - the traditional telephone network and the Internet.
At the core of the Quadro is the Call Manager running on rock solid Linux software. The Call Manager sends voice streams through the digital signal processor for voice processing. All this occurs in a 1.77” tall box no larger than an 8.5 x 11 sheet of paper.
