</div>Dear Joćo,<br>
<br>
As I write it's not phones fault of echo. If you are interesting, phone<br>
is DPH-150S from D-Link. This phone allow two SIP accounts. One is<br>
registered to FS and another to my phone provider. Same phone, two<br>
accounts. When using phone provider's account there is no echo. When<br>
using FS account, there is echo. So the handset does not have any<br>
problem. And I am not talking about hands-free.<br>
<br>
I did provide info for start. And I am asking where to dig to find the<br>
problem. If FS does not remove echo, then who does? In VoIP-FS direct<br>
connection who removes echo then?<br>
<br>
Thank you.<br>
