being ideal.

If You Need to Improve the Rx Level
If the Rx Level measurement is between -6 to -9 dB, and IP phones are
used, take the following steps to increase the gain for the Triton analog
trunk to IP phone connection:
1. Go to VoIP Board configuration and click the Advance button.
2. Increase the Transmitting gain to IP Extension to 9 for the Triton
Analog Trunk. (Do NOT change the gain in the trunk property of the
Triton Analog Trunk Board, since it may impact the echo canceller
performance.)
If the Rx Level measurement is worse than -9dB (for example, -10 dB) you
should contact the CO to adjust the line loss to the acceptable range.
