Today, VoIP communication is commonly used to make calls online. The use of VoIP has become so popular because it allows users to make long distance and international telephone calls over their internet connection at a fraction of the cost associated with PSTN and mobile network providers.
With virtual telephone numbers now available from websites, such as mydivert.com, the VoIP telephone can now be used to make and receive calls just as you would with any other traditional telephone. In order to do this the VoIP user can use software on their PC, which will work in a similar manner to skype, with a headset and microphone, or they can use a hardware device such as a VoIP telephone or ATA adaptor.
For VoIP to replace the traditional landline telephone, clear 2-way audio, reliable transmission of DTMF tones, and connection availability are important issues.
The most significant factor that affects the call quality and functioning of the VoIP client is the speed of the internet connection used for making and receiving phone calls. The overall quality and reliability of your VOIP communications are completely reliant upon the quality, reliability and speed of the Internet connection that it uses. The internet speed (or bandwidth) in both UP and DOWN directions is important. A minimum bandwidth of 128 kpbs is recommended for VoIP calls.
Another consideration is the means used to make and receive calls. In general a VoIP hardware device has several advantages, and produces far better results than a software softphone or dialer. Some of the advantages of the hardware based solution include:
# A VoIP hardware device remains available and connected when your PC is turned off.
# A hardware VoIP telephone is not impaired when your PC is under heavy load (running multiple applications, or games etc.)
