Figure 66. Setting trunk In Call Routing to an AA
5. Call from one trunk to the testing reference trunk. You should hear a 1kHz 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, -12dB, no change is needed.
If the reading is -15 dB to -18dB, 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.)
