VoIP White Paper LibraryThis library of white papers will help you optimize the benefits of VoIP in your corporate communications.
To say that the VoIP revolution has improved and expanded the functionality of corporate communications in the past decade is quite an understatement. However, along with the incredibly positive impact of VoIP, it has created many challenges in the resulting hybrid environment of PSTN (traditional) telephony and VoIP.
To help meet those challenges, we have compiled this library of white papers to help optimize the benefit of VoIP in corporate communications.
We have compiled a library of application notes to demonstrate how Xorcom Astribank XPP Technology can enhance and improve the communications in a variety of business settings.

Battlefield Open Source PBX and Proprietary PBX
A New Perspective on Open Source PBX
Open Source is 18 percent of all PBX sales in North America. It now accounts for more new lines than any single proprietary PBX or key system manufacturer. While an Open Source PBX can be free, it pulls through a lot of revenue for businesses in the trade. Businesses that install an Open Source PBX are spending substantial amounts of money on GUIs, PBX appliances, gateways, SIP phones, VoIP trunking and installation. At the same time, with costs that can be 25-50 percent less than a proprietary PBX or key system, eight of 22 vertical industries have more returning customers than new ones. In fact, returning customers are now the majority of the Open Source PBX market.
Thus opens a new white paper recently compiled by the Eastern Management Group, a global telecommunications research and consulting company.

Why is USB2 the Ideal Interface for Asterisk?
The USB 2.0 interface provides a theoretical speed of 480,000,000 bits per second. A typical uncompressed phone conversation uses about 64,000 bits per second per direction, plus some overhead; in total less than 200,000 bits per second per phone call is used. Thus, the theoretical concurrent number of conversations that the USB 2.0 interface can handle is 480,000,000 divided by 200,000: roughly 2,400 calls for a single USB 2.0 port. This is a theoretical number, of course, and the typical host processor will not be able to handle this amount of concurrent calls, but it gives a clear answer to the question: “Can the USB port support heavy telephony traffic with multiple Astribanks?”
Connecting multiple Astribank units to a single USB 2.0 port is easy: simply use a USB 2.0 Hub to connect many Astribank units.
