<div><br></div><div><br></div><div>I have attached three documents which contain the related slice</div><div>for the problematic call in question:</div><div><br></div><div>[i] SIP Trace</div><div>[ii] RTP Trace</div><div>
[iii] RTP Proxy log</div><div><br></div><div style>Not on [iii], as you know there are two sessions per call. The first has packets relayed from both</div><div style>caller and callee for the inbound part. The second session (ie, outbound) has 0 packets relayed</div>
<div style>because the firewall is burning the packets both ways.</div><div style><br></div><div style>Not to sound redundant, this is one of the very few cases where we experience such problems.</div><div style>All other calls work as expected under the same environment.</div>
