WoIP: the Video Softphone

open source softphone
The voice-data convergence debate is over. VoIP is an established, robust technology having the requisite quality of service for business communications. Currently about 11% of all phone calls use VoIP at some stage in the connection.
This technology reduces communications costs and simplifies network management, but the really big business benefits come from real-time communications applications.

Our Softphone is a free and simple software that will enable you to make free calls anywhere in the world in minutes. It is quick and easy to install. Just download it, register, and within minutes you can plug in your PC headset and call everybody on any Network. That is what makes us unique. We are not a close network where you can just call your friends. You can use our gatekeeper to call:

1) Another VoIP softphone
2) Another VoIP phone
3) A PSTN phone
                                           4) A GSM phone.

Our calls have excellent sound quality and are highly secure with end-to-end encryption. In a few weeks we will have also the Video feature. A live transmission that works also with low bandwidth. For high quality video conferencing you do not need anymore high sophisticated hardware and high bandwidth.
You just need a good web cam (the better the cam, the better of course the video quality).

About Video Conferencing


Driven by cost, efficiency and quality concerns, the installed base of ISDN (H.320) videoconferencing users is moving to IP (H.323). Often this comes as part of a broader consolidation of circuit-switched traffic onto IP packet backbones

Many organizations look at the unused capacity in their IP packet data networks as a potentially “free” substitute for the dedicated ISDN lines. Some also think their IP networking staff could take over for the people who have been running their ISDN videoconferences. And features of the newer H.323 systems, like centralized management and simplified call setup for users, also help cut costs and improve efficiency.

Another major driver for conversion to IP is call quality.
ISDN lines have a habit of developing bit loss, and of then dropping out, requiring either manual or automatic redialing.
Meanwhile the conference is either on hold or operating at a much poorer level of video quality, because it is trying to function on the remaining bandwidth.

Even in very well-managed ISDN videoconferencing installations, where users actively track and pursue the quality of their calls and ISDN lines, call success rates run only to 90 and 95 percent.

For organizations that do not have a rigorous quality program, success rates can fall to as low as 60 percent. (Successful calls start on time, the quality is sufficient for the meeting to proceed, and the call is not dropped or interrupted.)

In the past, IP networks have not been considered super reliable, because they do not yet hold up to the 5-nines standard of voice telephone systems and the PSTN.
But compared to the call success rates of videoconferencing on ISDN, IP videoconferencing’s simplified call model, corporate network control and centralized management can offer a substantial quality improvement.

Another factor to consider is that ISDN is no longer a primary focus for the telecom providers, so its quality is not likely to improve dramatically, whereas IP is a big focus both for the carriers and for the enterprise.
So future trends also lead us to the conclusion that the more reliable transport is and will be IP.

IP-based conferencing also promises increased functionality—for example, higher video rates, better data handling and integration with other enterprise databases for scheduling and user identification.
These features are of interest to the enterprise, but it is cost, efficiency and quality that drive conversions from ISDN to IP today.


Is VoIP Secure?



If you’re planning to deploy VoIP, you’ll need to take some steps to make the data network more secure, especially if you haven’t performed an overall security audit recently.

You might be shortchanging yourself.
When it comes to outside communications with VoIP, weigh the potential cost savings and efficiencies gained by converging technologies against the risk.

If you’re already transmitting and receiving sensitive data over the Internet, you’ve gone to considerable lengths to protect that data, which is almost surely more sensitive than your voice traffic and no less vulnerable to attack.
These safeguards can be leveraged to help secure VoIP over the Internet.


But What About Packet Sniffing?



While it’s technically possible to sniff voice packets, it’s a lot more difficult than tapping into a traditional phone transmission. Let’s consider what it would take to tap into VoIP.

The first step in sniffing a conversation is to gain physical access to the packets.
This means having access to the switches and/or the corporate backbone network. But those same switches carry critical corporate data, which is far more sensitive than your conversations.
If you’ve secured data against sniffing, you’ve secured voice. If you haven’t protected your data, voice packet sniffing isn’t your most serious security problem.

But let’s say an intruder gains physical access, despite your best efforts.
If it’s a traditional phone line, he’s practically listening already. But if you’re using VoIP, he really has his work cut out for him.

First, consider what it takes to tap a traditional phone line. If the conversation is still in analog format, the intruder simply taps onto the line using a “butt set”—which was formerly reserved for telephone repairmen, but now available at hardware stores—and starts listening.

Traditional telephony uses time-division multiplexing for trunk groups—as opposed to packet multiplexing— so picking out a single conversation from a digitally multiplexed bundle of conversations and decoding the 64 Kbps pulse code modulation (PCM) is relatively easy.

Compare that with pulling a conversation out of an IP transmission.
Voice packets are buried deep inside a sophisticated protocol stack.

The intruder has to know what the physical format of the information is; decode the Ethernet packets to find a single flow between two points; decode the IP layer; decode the transport-layer (layer 4) protocol—probably UDP—and then, finally, decode the voice packets, which could be encoded in a wide range of formats. And he has to do it in real time.


So, Is VoIP Secure?



It’s a lot easier to listen to a conversation over a cubicle wall than it is to tap a VoIP call.
The odds are that you actually could improve your level of telephony security as compared with traditional telephony simply by piggybacking your voice onto the more secure data network.

There’s even a question as to how secure VoIP should be.
For instance, there are legitimate concerns from the law enforcement community about whether advanced voice networks are “too secure” for court-sanctioned wiretapping.

VoIP is probably as secure as traditional telephony and a lot more secure in most cases than your cellphone.
