Line Controls
If you need to adjust the volume of conversations through the system, you
can adjust each line individually. The default settings compensate for loss
created by TalkSwitch and a portion of the loss created by your lines. We
recommend that you adjust the level for each line separately, as the
characteristics of each line may vary. These controls only affect the volume
heard by the caller. To calibrate the lines once a line is added or changed,
click the ‘Calibrate Lines’ button.
Extension Controls
These controls allow you to increase or decrease the volume level of calls and
system prompts heard at each extension.
VoIP Codec Selection
All 3 codecs are active by default. The preferred codec is G.729
(approximately 20Kbps bandwidth). For example, if you have a ‘lite’ version
of a broadband service, you do not have enough bandwidth to support G.711
(approximately 100Kbps bandwidth) or G.726 (approximately 50Kbps
bandwidth) codecs. ‘Lite’ connections typically have only enough bandwidth
to support G.729. In this case, uncheck the G.726 and G.711 codecs so that
the system does not attempt to use these codecs when setting up a call.
