The European justice service Eurojust together with the police and prosecutors currently investigate how internet phones like Skype technically and legally can be tapped. VoIP Internet phones are now practically not to be tapped because of technical boundaries. Several countries say that Skype refuses to give the encryption codes for making tapping calls able for the authorities.
China spies on Skype users
China keeps chat and phone calls from Skype users closely and see censorship as the speakers words like independence or Tibet are used. This is what Canadian researchers from the University of Toronto recently discovered. Read the rest of this entry »

When it comes to communication, VOIP has long been loved for its cost effectiveness as users can practically call anyone they desire, anywhere in this world. They only need to pay a small charge but usually this service is available free if you make PC to PC calls with renowned VOIP providers like Skype and Comcast. Free video conferences can also be enjoyed if you have a dependable webcam plugged into your PC.
All the same, there has to be a lot of changes made to VOIP before it can be considered a flawless mode of communication. The subject of cost effectiveness has already been covered but many are still seeing red over the quality and consistency of VOIP calls. The quality of voice calls have seen considerable improvements over the years but those who are used to the almost faultless voice quality when using old fashioned PSTN phones are reluctant to make VOIP their main method of communication.
VOIP calls are very much influenced by bandwidth where an extremely stable Internet connection is needed in order to make VOIP calls. Read the rest of this entry »

Voice Over Internet Protocol (VOIP) is getting more popular day by day and is proving to be even more desirable than the average telephone system that utilizes the circuit switching concept. Circuit switching can be described as a kind of switching method in which a connection link is maintained so that it never switches off. This is achieved using pre-defined circuits. Only after the last portion of data is sent, will the connection be turned off.
In contrast, VOIP is based on the packet switching technique whereby the connection is kept open in the blink of an eye, long enough to let miniscule chunks of data or packet to be transported between two varying systems. The first computer delivers the data by breaking it down then attaching special instructions detailing the destination of this particular information. After the second computer receives the data, it will immediately piece together the packets and restore them to the original structure.
That being said, one can tell that VOIP and its packet switching method is an efficient form of communication compared to circuit switching which is slowly losing its appeal. Circuit switching is the technique behind Public Switched Telephone Network (PSTN) phones therefore it is much more exorbitant to make international calls using a conventional phone compared to using VOIP. This is because a dedicated PSTN line is being rented by the minute whereby a VOIP network can be shared amongst other users instantly. Without circuit dedication, there will be no extra costs for a single person to bear.
VOIP and packet switching cannot be compared to the PSTN’s network as a dedicated circuit gets you better quality. Information will always be delivered more efficiently, hence the higher costs. A VOIP’s open circuit will attract untoward congestion and hence cause bad call quality. Although this is the case, VOIP voice quality can be made better with TCP protocol so there should be problems attached to packet switching if you want to make VOIP your choice of communication.

Regardless of any technology or household gadget, we definitely would want to maximize its performance. Similarly, it is possible to maximize VOIP experiences. To achieve this, one would require high quality as well as reliable IP phones. IP phones are better known as Session Initiation Protocol or SIP phones.
Why SIP phones? In general, SIP is the terminology used for VOIP signaling. What is the difference between standard landline phones and IP phones? There is a special internal ATA, that is, Analogue Terminal Adapter available with IP phones.
You will not require any special software or hardware to connect IP phones to the VOIP network. You simply have to plug them to the ADSL Internet router. Another model of IP phones are those with Ethernet ports. This enables one to use RJ-45 cables with LAN connection. You can just connect the IP phones to this port and it will not require additional plugging onto electricity outlet. Read the rest of this entry »

VoIP phones are the phones with voice-over-Internet protocol technology. VoIP is the technology used for transmission of audio or data as packets over the Internet to either a user or computer to a fixed telephone network. VoIP is growing in popularity because it’s very valuable for their high quality, low cost and incredible features. VoIP is gaining respect as a viable solution for the business needs as well. VoIP enables telephone calls either for free or for only pennies in comparison to traditional telephone services.
There are many different ways to use VoIP. For some services, you need a computer, a high-speed Internet connection, an instant messaging program, speakers, a microphone, a telephone adapter for converting standard phones in VoIP phones, or a VoIP phone.
The use of VoIP services, you can simply a microphone and speaker to communicate with your callers. You need a high-speed Internet connection to allow your calls in real time, and you also need a sounding board and computers up to date with VoIP technology. Read the rest of this entry »
