Call waiting

By default, call waiting is on. You will hear the pling if you are talking and someone else is trying to call you. You can switch between the calls by pressing the "R-Key". If you want a busy tone to be given to the other caller, turn off call waiting by changing [User 1] "CW Setting" to .

Sound level and quality

You can adjust the volume of your phone by changing the "FXS Port Output Gain" and adjusting the volume of your counterpart by adjusting the "FXS Port Input Gain" - both on the [Regional] tab. An increase of 3 corresponds to a doubling of the volume. Note, however, that too much "FXS Port Input Gain" causes echo at your end and should be avoided.

If others experience that you audio is choppy, you upstream speed is too slow. Complain to your provider and look under "Solutions to typical problems" below.
