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.
Note
To create a test tone, follow these steps:
Procedure
Step 1
Place a call.
Step 2
After the call is established, press Help twice, or press Settings > Status > Call Statistics.
The Call Statistics screen and Tone softkey should appear.

Press Tone.
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.
