SPA 3102 - PSTN Gateway Echo

Hi.                  

I have one SPA3102 with last firmware.

I use it to make VOIP calls with PSTN line.

Calls come in on the PSTN lines and are routed to our 3CX server by SPA3102.

The 3CX server connects the calls to the correct IP phone extensions.

The echo is present during every call (making or receiving).

I'm from Brazil.

Can someone help?

Thank You.

You should match up the impedance setting for your country.  The default setting on the unit is 600 for U.S.  I believe Brazil is 900.
