<div>Hi Ryan,</div>
<div> </div>
<div>Are the SIP and RTP ports are randomly selected or there are specific ports for these? Unchecking</div>
<div>random port selection option on the device/softphone may help.</div>

<br>i.e. before iptables. The packets are being dropped for whatever<br>reason and never reach the asterisk process. Check your iptables and<br>RTP port range, and perhaps try changing it.<br><br>Luki<br><br>_______________________________________________
