PX24N (Nano): Revolutionary IP PBX
Perhaps, it is the first time in the world!
PX24N (Telesis Nano) is a next-generation IP PBX to home and small business market. It is designed to fit the expectations of the market now and in the future. Although most small IP PBX products miss on features, the PX24N differs. The PX24N has many features, which can be built onto large IP PBX systems only or even not.

Formula is simple but attractive like the PX24N itself.
3 analog DC loop trunks (FXO ports), 3 analog subscribers (FXS ports), and 10 IP (SIP, or H.323, or xSIP) users (local or trunk) are located in a unique box, featuring an executive digital phone too.

The photo above is not only an executive telephone set but much more inside!...
The PX24N is intuitive and easy to install and can be up in minutes only. The sleek box design and revolutionary features make it an ideal communications platform for today`s dynamic businesses and home users as well.
The PX24N is a complete solution in the same box, which also features an executive digital telephone offering advanced telephony tasks.

FXS, FXO, power, headset, microphone, handset connectors are located at the bottom.

10/100 BaseT ethernet on the side provides VoIP, API, maintenance, billing connectivity.
Easy installation without any special tools, easy administration and easy maintenance make the PX24N an ideal choice for experts as well as novices, who look for a SoHo platform. The PX24N eliminates additional hardware costs and recurring expenses.
The PX24N is a converged communications system with TDM and IP connectivity at the same time. It provides FXS, SIP, xSIP, H.323 for the local connectivity. Standard SIP and H.323 make the PX24N fully compatible with all industry standard IP devices including IP voice and video phones. Consequently, it is possible to use a mixture of legacy TDM and IP based terminals like phones in the same system. Furthermore, the PX24N offers similar features and services to both TDM and IP users, that make the life easier.
Similar to local connectivity, either provider or inter-office networking is achieved with FXO, SIP and H.323 interfacing. The PX24N can register to multiple TDM or VoIP providers at the same time. This results in flexibility for multi-path and multi-provider access applications. Enhanced routing algorithms allow least cost routing, as well as alternate routing, for the same or different destinations automatically.

The PX24N is a converged communications system with TDM and IP connectivity at the same time. Click on the image above to enlarge it.
The PX24N also hosts Telesis WebPhone, which is a SIP softphone or client applet. The applet can be run from any Java enabled web browser. Consequently, the embedded feature phone or any other TDM or IP terminal can be accessed wherever is an access to the Internet. That means free calls to your home or office throught the world. A web browser, a microphone, and a headset are sufficient to make calls towards the PX24N and its terminals.
There are more!..
A 100 hours (6000 minutes) capacity DVR (Digital Voice Recorder) exist in each PX24N. DVR brings personal conversation recording capability, voice mail (VMail) services, automatic call distribution and answering machine functions without any expense.
The PX24N supports Telesis developed xSIP (eXtended SIP) protocol too. xSIP makes some value-added services (like busy diplay panel) in the PX24N to be applicable for VoIP calls too. Presently, Telesis offers two products with xSIP protocol. One is the ITS821 IP Phone, and another is freeware XPhone IP Softphone (PC and modile phone editions).
The PX24N supports Telesis developed Xymphony-API protocol too. The result is various telephony tasks such as dialing, call transfer, call park, call retrieve, conference, conversation recording, and display of port status with using a computer. Moreover, Xymphony-API client utility (software) Telesis XCom is a freeware utility.
