    Troubleshooting echo

    Abraham

      Hi!

      About echo in voice network, how does the input gain and output attenuation parameters affect echo?

      And also about the value of ERL worst case (Echo return loss). If I define and ERL of 3 db does this means my my voice gateway would not be able to detect echo with ERL above 3dB (let's say 4dB ERL) for example

       

      Thanks
