3CX has released a new version of their 3CX Phone System for Windows.

The new version of the IP PBX, version 5.1, includes 3CX Tunnel, which channels VoIP traffic over one port. This both simplifies the firewall configuration and makes it easier for remote access to the company PBX.

“We know how important it is for businesses nowadays to have remote workers and branches seamlessly integrated to their company’s phone system, and the addition of the 3CX Tunnel to 3CX Phone System for Windows facilitates this process,” said Nick Galea, CEO. “The 3CX Tunnel, unlike other similar tunneling protocols, is not proprietary and can be used with popular VoIP softphones and hard phones. This is ideal for businesses, as they can use a variety of telephone options with their IP PBX depending on their needs and budget.”

"The Future of Open Source VoIP is Asterisk 1.6" was mentioned a few times in the past here and elsewhere and now it has arrived, at least the beta, Asterisk 1.6 Beta1. I have been plying with it from SVN but the Asterisk dev team announced that the official release of beta to get more people involved in testing.
I idea is more people test the release 1.6, sooner it can leave testing stages and go into main stream release.
Also remember that Asterisk 1.6 will be the first major release of Asterisk since 1.4, which was released just over one year ago. This release contains a number of new features, as well as architectural improvements for improved performance. The changes since asterisk 1.4 could be found here. The Readme file for the release is here.
I also have been testing A New Channel Driver For Asterisk, chan_unistim. with Nortel phones as I have them in a VoIP Solution that I have proposed to an institution and myself is using one of them.

The SIP based communications are becoming a preferred interconnection in this growing market, touted by some to be $22 Billion. But as with any communication method, there are some gotcha’s hiding and waiting to pounce on you the day you go production. So how do you avoid the hassle, you test with proper testing procedures and tools. So TekVision is in the market, to take it’s portion of the $22 Billion by providing a testing service, a testing Lab.
TMCNet’s Erik Linask writes how the whole procedure works and how you stand to gain by testing with them.

The SPA962 VoIP telephone will appeal to businesses using a hosted IP telephony service, an IP PBX, or a large scale IP Centrex deployment, with it’s array of features.

Here are some features that stand out;

• Full featured six line business class IP Phone supporting Power over Ethernet 802.3af
• Connect directly to an Internet Telephone Service Provider or connect to an IP PBX

I like the fact that it has a color Screen!Standard features on the SPA962 include six active lines, dual switched Ethernet ports, 802.3af PoE support, a high resolution color display, speakerphone, and a 2.5 mm head-set port. Each line can be independently configured to use a unique phone number (or extension), or can be configured to use a shared number that is assigned to multiple phones. The power supply for the SPA962 is sold separately and will be required if PoE functionality is not implemented.

Comprehensive Interoperability and SIP Based Feature Set
Based on the SIP standard, the SPA962 has been tested to ensure comprehensive interoperability with equipment from VoIP infrastructure leaders enabling service providers to quickly roll-out competitive, feature rich services to their customers. With hundreds of features and configurable service parameters, the SPA962 addresses the requirements of traditional business users while leveraging the advantages of IP telephony. Features such as easy station moves, presence, and shared line appearances (across local and geographically dispersed locations) are just some of the many advantages of the SPA962.

Carrier-Grade Security, Provisioning, and Management
The SPA962 uses standard encryption protocols to provide secure remote provisioning and unobtrusive in-service software upgrades. Linksys secure remote provisioning tools include detailed performance measurement and troubleshooting features, enabling network providers to deliver high quality support to their subscribers. Remote provisioning also saves service providers the hassle and expense of managing, pre-loading, and re-configuring customer premise equipment

FCC, Federal Communications Commission, states that "Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line. Some VoIP services may only allow you to call other people using the same service, but others may allow you to call anyone who has a telephone number - including local, long distance, mobile, and international numbers. Also, while some VoIP services only work over your computer or a special VoIP phone, other services allow you to use a traditional phone connected to a VoIP adapter."
Let’s see how others describe it.
Howstuffworks tries to give you much information as possible with the article "How VoIP Works". I have gone through the complete article and found it to be ok. My writing ability is not as good as Robert Valdesz (It is getting there), otherwise I would try to write a simpler version as well.
He starts with how VoIP Works, How current PSTN, Public Switched Telephone Network, works which continues to the bits and bytes involved in a regular Telephone call, Advantages of VoIP, Disadvantages of VoIP and Codecs, softswitches and protocols.

All in all you get an idea of How VoIP Works but I wonder if the article ib being kept updated, for instance about E911, A lot has changed since it was written. So that is "How VoIP Works" until my writing improves. If I find any other VoIP introductions, I will Post them here.
