No. Prepaid calls can be made from any computer (for example, home and office). However, we suggest you exercise caution if you make Prepaid calls from a shared computer. Clear the account number/User ID and PIN fields after ending your calling session. The use of public computer terminals to make Prepaid calls is discouraged.

How can I improve the sound quality of the call?

One of the factors that can affect sound quality is the Internet bandwidth available during your call. Try to avoid making calls during peak Internet usage hours when traffic is high. Another tip is to use a headset with a built-in microphone. This will help eliminate echo and ensure better sound. Adjust the microphone volume so that your speech is not too loud.

I hear an echo while making a call using the speaker. What should I do?

We recommend using a headset as this reduces the echo effect. If you are using speakers, the feedback from them may cause the person on the phone to experience some echo. Our software will detect this echo and will automatically try to compensate for this, but it may not be able to eliminate all traces of the echo. Try to move the microphone as far away from the speakers as possible.You can also try lowering the speaker volume. This will usually reduce the echo.

How do I change the sound volume?

You can control the speaker and microphone volume by manipulating the volume control knobs on the dialer. Alternatively, open the Windows Volume Control by selecting the Start menu, followed by Programs, Accessories, Multimedia, and Volume Control.

Why do I get a distorted or choppy sound sometimes?

The distorted or choppy sound is due to data packets of the speech being lost or dropped. This could be due to a bad Internet connection, low bandwidth, sound card problems, insufficient memory, or a slow CPU. Always ensure that the latest sound card driver is installed. It is advisable to close unnecessary programs to conserve memory and CPU load, when you use the Prepaid Calls Service. Try to make calls during non-peak hours to ensure better bandwidth.

Why can't the receiver hear me immediately after picking up my call?

Due to the network, the receiver will experience a five second delay before hearing your voice. You may wish to inform the receiver of this limitation.

I get a busy tone after my call is connected, what is the cause?

It means that the phone number that you've dialed is engaged or busy. The phone gateway that the PC-to-Phone Service communicates with is unable to terminate the call automatically. Click hang up to terminate the call manually and try again later.
