5. Call from one trunk to the testing reference trunk. You should hear a 1 kHz tone playing at the originating
side.
6. While the tone is playing, measure the Rx Level at the trunk that is making the outgoing call.
If the reading is less than -6 dB, for example -3 dB, take the following steps to attenuate the gain for the
Triton Analog Trunk to IP phone connection:
a. Go to VoIP Board configuration and click the Advance button.
b. Set the Transmitting gain to IP Extension to 3 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 reading is -6
dB to -14 dB, for example, -12 dB, no change is
needed.
If the reading is -15 dB to -18 dB, take the following steps to increase the gain for the Triton Analog Trunk
to IP phone connection:
a. Go to VoIP Board configuration and click the Advance button.
b. Set 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.)
