DTMF Tones Echo
Back to the
Analog Line Card
The pcXset software cannot make external calls through any Analog Line
Card port, but calls to internal extensions are successful. Typically, the call
fails the first time, but succeeds if you click Redial.
Description
This error occurs when DTMF tones echo from the PC speakers back into
the microphone, causing the Analog Line Card to receive each outpulsed
digit twice.
Solution
Select Options > Display > Substitute For DTMF Tones . This option
replaces DTMF tones with clicks. The Analog Line Card ignores the clicks
when they echo back to the TLIM. You can also use headphones to
alleviate this problem.

The likely cause of this error is lack of full-duplex audio.
A similar message may appear in the log file:

card while another application is recording audio. It also happens when
the audio driver does not support full-duplex audio.
You can use Windows Sound Recorder to verify that the audio subsystem
supports full-duplex by running two Windows Sound Recorder
