VOIP Phones – An Affordable Broadband Communication Technology

December 4th, 2009



Cordless VOIP phones have become increasingly popular because they afford the caller a bargain-priced way to communicate. Unlike conventional international and long distance telephone calls where you pay quite high charges per second, the VOIP call will only cost you accordant with what you pay for your internet access. So if you have flat rate monthly internet billing, then you can make as many calls including interstate locations as much as you want without being billed for any further costs.

Cordless Skype telephones give the user extra leverage when it comes to communication due to the fact that the same high speed internet service that is used for voice signals may also be used for other data transfers such as web browsing. With Voice-Over-IP Phones, you are able to do away with numerous bundles of telephone wires and the resultant holes through ceilings.

There are primarily three means to connect a wireless VOIP phone. The most common method of connection is through the use of a regular VOIP phone – this could even be simply a run of the mill mobile telephone handset with VOIP capability – meaning it is able to transmit over the web in lieu of the normal telephone system. They also make VOIP phones via alteration of a normal telephone. In this instance you’ll need an adaptor so that the regular phone can be made to transmit digital audio signals via the net. A third type is the soft phone. In this example you’ll use your computer speaker and headset as the phone. The pc will also have a program that will enable you to transmit the resulting digital audio signals over the internet.

It is extremely critical to use a high speed ethernet connection for your VOIP Phone. A low speed web connection will cause your connections to break very often, resulting in inferior voice quality. If you are buying a usb VOIP Phone from a shop, ensure that you have access to fire and emergency services such as 911.

There are many things to think about if you are using a wifi skype telephone. You’ll need to consider the communications standards that the phone offers. You will also have to determine if your wireless and Web connections are able to support them. Again, you’ll have to look into whether it comes with features like conferencing so you are able to talk to more than 1 people at a time. It might be practical to get a wireless Voice-Over-IP Phone with a LCD or LED screen so you are able to place calls or otherwise make use of the phone in dimly lit areas. You’ll need to find out what standards employed by the Voice-Over-IP are directly supported by your computer. This is vitally critical if you are using an adaptor to make the telephone work. You’ll also need to figure out this specification if you plan to use a Voice-Over-IP Phone handset.

Wireless Skype phones provide a very cheap way to communicate with family. You’ll spend much less money to talk interstate or overseas.

Introduction to VoIP Technology

October 28th, 2009



Voice over Internet Protocol, also called VoIP or Internet telephony, is the transportation of voice conversations over the internet or through any other IP-based network rather than the public switched telephone network (PSTN).

Protocols which are used to carry voice signals over the IP network are commonly referred to as Voice over IP or VoIP protocols. Some cost savings are due to utilizing a single network to carry voice and data. Users that have existing underutilized network capacity can use VoIP at no additional cost. VoIP to VoIP phone calls on any provider are typically free, while VoIP to PSTN calls generally costs the VoIP user.

There are two types of PSTN to VoIP services: DID (Direct Inward Dialing) and access numbers. DID connects the caller directly to the VoIP user, while access numbers require the caller to input the extension number of the VoIP user. Access numbers are usually charged as a local call to the caller and free to the VoIP user, while DID usually has a monthly fee. One can also find DID that are free to the VoIP user but charge the caller instead.

Key features of VoIP:

VoIP can facilitate tasks that may be more difficult to achieve using traditional networks, such as:
• Routing phone calls over existing data networks to avoid the need for separate voice and data networks.
• Incoming phone calls can be automatically routed to your VoIP phone, regardless of where you are connected to the network. Take your VoIP phone with you on a trip, and receive incoming calls whenever you are connected to the Internet.
• Free phone numbers for use with VoIP are available in the USA, UK and other countries from several organizations.
• Call center agents using VoIP phones can work from anywhere with a sufficiently fast and stable Internet connection.
• Many VoIP packages include PSTN features that most Telcos normally charge extra for, or may be unavailable from your local Telco, such as 3-way calling, call forwarding, automatic redial, and caller ID.
• VoIP allows users to travel anywhere in the world and still make and receive phone calls.

Flexibility:

• VoIP service users can make and receive local phone calls regardless of their location. For example, if a user has a US phone number and is traveling in Europe and someone calls the US phone number, it will ring in Europe. Conversely, if a call is made from Europe to US, it will be treated as a local call. Of course, there must be a connection to the internet, for e.g. Wi-Fi, to make all of this possible.
• Users of Instant Messenger based VoIP services can also travel anywhere in the world and make and receive phone calls.
• VoIP phones can integrate with other services available over the Internet, including video conversation, message or data file exchange, in parallel with the conversation, audio conferencing, managing address books and passing information about whether others (e.g. friends or colleagues) are available online to interested parties.
