Details for each setting are shown in the table below.
Setting
Description
Dialing Timeout
This setting configures the maximum amount of time in seconds between touch tone key
presses the system waits before assuming the phone number or Skype shortcut entry is
complete. This setting can be safely adjusted based on user preference.
Tx gain
Transmission gain setting to adjust the transmit voice volume. Each increment can
increase or decrease voice level by 3db.
Rx gain
Receive end gain setting to adjust the receive voice volume. Each increment can increase
or decrease voice level by 3db. In case remote party voice echoes back through the line,
this setting can be adjusted to a negative value between ‐3 and ‐5 to address the issue.
Enable Echo Canceller
This setting enables built‐in software echo‐cancellation algorithms used to improve voice
quality. If lines between PBX and VoiceGear SkyBridge have excessive echo or static, this
setting should be enabled.
7.2.4 Advanced Configuration
Advanced analog hardware configuration allows users to profoundly change the behavior of the installed analog
hardware. It is not recommended to adjust these settings without having an advanced understanding of the
system.
