Checking that Microphone and Speaker are Functioning Properly

The easiest way to check if both microphone and speaker are functioning properly is by using pjsua and looping the microphone to the speaker in the conference bridge:

  1. run pjsua:
     $ ./pjsua
  2. loopback microphone to the speaker:
    >>> cc 0 0
  3. Done

Now whatever captured in your microphone will be played-back locally to your speaker.


This step is not recommended for PDA application since on PDA, the echo suppressor will cut the microphone signal once it detects that something is playing in the speaker.
