Hi,<br><br>I used to use Zoiper IAX to connect to my asterisk server from remote site. On asterisk CLI, I can see my zoiper client registered and stay on line. HOwever, I don't know why now I can't call this client. It always show up as "Unable to create channel IAX2 (Cause 20 Unknown)<br>
<br>I am using Asterisk 1.8.7.1<br><br>CK<br>
