[cisco-voip] Distant tunnel like sound

[Brian Feeny]

You should be looking at the levels, and adjusting the gain, attenuation and coverage to get an Echo Return Loss of at least 6db.  Once you have that, you should be good to go.  The telephony troubleshooting book by ciscopress has an excellent section on doing this.
