<p dir="ltr" style="MARGIN-RIGHT: 0px">Hello,</p>
<div> </div>
<div>I am getting in contact with RoIP.</div>
<div>We are using the ACID install with DMK URI to connect a half duplex radio without COR line. So we have connected PTT (pin1), GND (pin20) , MIC_AC(pin 21) and LEFT_AC (pin 22).</div>
<div>We have also installed the iaxrpt client and the voice is received in a remote radio perfectly. But we have the problem in the way back. If you speak from the remote radio, the voice signal arrived at the LEFT_AC of URI but if it is not processing. Nothing is listened in the iaxrpt client.</div>
<div> </div>
<div>I had tried to comments the txctssdefault,rxctcssfreqs and txctcssfreqs because i have introduced ctcssfrom=no and also i invert the txmixa and txmixb settings but it didnīt work.</div>
<div> </div>
<div> The usbradio.conf looks like this:</div><span lang="ES-MODERN">
