To adjust Echo Suppression and Line Loop Length settings:
1. If line recalibration and checking parallel devices do not resolve audio echoes, go to
the Advanced Configuration section on the PSTN Settings page.
2. Under Echo Suppression for the affected line(s), select Aggressive.
3. Click to save the settings.
4. Test your line(s) by establishing a call under the same conditions in which the echo
condition was previously heard.
5. If the condition persists, leave the Echo Suppression set to Aggressive, and adjust
the Line Loop Length. This setting compensates incoming and outgoing audio
levels depending on line loop length. Try Medium first, click , then make a
test call.
6. If the condition persists, try Short, click , then make a test call.
You may need to test different combinations of Echo Suppression and Line
Loop Length settings to achieve the desired results.
