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.
If You Don’t Have the Milli-Watt Test Number
If you don’t have the local CO’s Milli-Watt Test Number, you can follow the steps below to measure the line
loss when calling two local trunks:
1.
Copy C:\Post Office\Phrases\Lang1\phrase9900 to C:\Post Office\Phrases\LangCustom folder. Rename
it an unused phrase name, for example, phrase0990 (the number must be less than 1000).
This phrase is a 1 kHz test tone.
2. Select an unused AA and set the AA to play the prompt phrase you named in step 1 (0990 in this example).

3. Set the Timeout to Repeat Current Level.
