<div dir="ltr">Hello,<div><br></div><div>I am using Freeswitch version 1.2.12 on Debian 3.2.46-1 x86_64. My main use case includes terminating calls through gateways.</div><div>In most of my gateways everything is working 100% right, but I have a private integration with a termination gateway provider which isn't working.</div>
<div><br></div><div>The problem is that when performing a bridge , the SDP negotiation is finishing but no RTP packet are sent to the gateway and I see the following lines in the log:</div><div>[NOTICE] switch_ivr_bridge.c:274 Hangup sofia/external/999112123752658 [CS_EXCHANGE_MEDIA] [DESTINATION_OUT_OF_ORDER]</div>
<div><br></div><div>If I capture the traffic I can see the following ICMP packet:</div><div> </div><div><div>6<span class="" style="white-space:pre"> </span>17.453667000<span class="" style="white-space:pre"> </span>144.76.108.53<span class="" style="white-space:pre"> </span>85.92.157.36<span class="" style="white-space:pre"> </span>ICMP<span class="" style="white-space:pre"> </span>242<span class="" style="white-space:pre"> </span>Destination unreachable (Port unreachable)<br>
</div><div><br></div><div>The strange thing is that if I reboot the machine, the problem is solved for one session and than keep reproduces on the following calls.</div><div>I eliminated all firewalls issue by disabling the firewall , and tried changing the hardware to Ubuntu but still the same behavior.keeps coming back.</div>
<div><br></div><div>Is there any know issue which might explain this?</div><div><br></div><div>Best regards,</div><div><br></div><div>Doron</div><br>
