Procedure for Creating a Test Tone
When measuring echo, make sure you first set the input and output levels to 0 dB gain/attenuation on
the trunk. This is set for the gateway (in Cisco Unified Communications Manager for MGCP) or under
IOS CLI for H.323 or SIP.
Step 1 Place a call.
Step 2 Once the call is established, press the Help button twice, or press Settings > Status > Call Statistics.
The Call Statistics screen and Tone softkey should appear.
Step 3 Press the To n e softkey.
The phone generates a 1004 Hz tone at –15 dBm.
For a good network connection, the tone sounds at the call destination only.
For a bad network connection, the phone generating the tone may receive echo from the
destination phone.
Step 4 To stop the tone, end the call.
For information on interpreting the results of test tone for volume and echo, see the following document:
