It is important to have a phone line that is not noisy since computers are more sensitive to background noises. It can pickup sound that is not obvious to the human ear.
A noisy line makes voice detection less accurate and might cause long delays at the beginning, or failed to leave a message on an answering machine or voice mail. There could be many reasons a line gets noisy.
Noise caused by a poor quality voice modem
If you use Voicent modem, you should not have this problem
Noise caused by the telephone line itself
You should at least check that:
-
All line jacks are firmly plugged in.
-
Your phone line is not too long. Try to use the phone line comes with the modem package.
-
Check special services on your phone line. For example, if you use a voice mail system, the special tone indicating you have voice mail might make the line noisy for outbound calls. Clean up the message in your voice mail should remove the special tone.
-
If you are using VOIP line, please make sure your internet connection has enough bandwidth. For example, if you are downloading a huge file while making a phone call, the line tends to be noisy.
Noise caused by the environment where the person receiving the call is in
If you are calling a cell phone and the cell phone happens to be in a poor reception area, you will have a noisy line. Cell phone service might drop calls or even missing the call altogether.
Same thing could happen if the phone is answered in a noisy condition, for example, a TV is on or someone else is talking laud.
There is nothing the system can do if the receiving
environment is noisy.
Connect a regular telephone to the modem PHONE jack. Use the phone to call the same number the modem just called. If the line is noisy, check the above item for solutions.
To hear exactly what the modem "hears" on the phone line, turn on the Record Initial Dialing feature of Voicent Gateway. In this mode, the gateway will record the audio starting from the time the phone is connected till the time it begins to play your message. The wave files are usually saved under "C:\Program Files\Voicent\Gateway". The audio file names are prefixed with pickup_ and ends with .wav.
You can listen to the audio recording file by clicking on the file name. If you do not hear obvious noise in the recording, please send your wave file to support@voicent.com.
To turn on Recording Initial Dialing, please click on the Voicent Gateway icon (where is it?) to invoke the gateway main window, then select Help > Record Initial Dialing from the main menu.
