If your softphone software does not provide an Audio-Test-Wizard, use this link Audio test to run this test from our website (click open and follow the instructions of the tuning wizard).

    c. Set your Speakers volume to a comfortable level. If you don't hear the speakers make sure the green and red audio plugs are connected to the proper PC jacks.
    d. Always set the Microphone volume to the lowest level feasible. Normally this level (in green color on the slider) is 20% of the slider's full scale, or even less. You can check and fine-tune this level on your first actual call. If no green color appears on the "Microphone Volume" slider - check the audio plugs connections.

  4. Some telephones may not pass the Microphone volume test and should not be used with Chat-Cord™.

More info: Basics of VoIP

The concept of "free telephony" was first introduced in 1995/1996. The idea is that your voice rather than traveling over your phone line can travel over your Internet connection. This is called Internet telephony or: "Voice over Internet Protocol/Packet" or VoIP. Data networks and VoIP use a method called packet switching. Packet switching opens the connection just long enough to send a small chunk of data, a packet, from one system to another. The sending computer chops data into these small packets, with an address on each one telling the network where to send them. When the receiving computer gets the packets, it reassembles them into the original data. This minimizes the time that a connection is maintained between two systems and reduces the load on the network. It also frees up the two computers communicating with each other so that they can accept information from other computers as well. VoIP technology uses this packet-switching method for voice communication, possible protocols like: H.323 and SIP. Protocols define ways for devices to connect to each other using VoIP. Also, they include specifications for audio codecs. A codec, which stands for coder-decoder, converts an audio signal into a compressed digital form for transmission and back into an uncompressed audio signal for replay. Chat-Cord™ is indifferent to which protocol is being used.
