<p><tt>Are you able to record a .pcap of this message sequence?

<span>Hi all,<br>
</span>
<div><br>
</div>
<div>Very strange case, OpenSIPS in the middle SIP transaction
ignores one end of the communication.<br>
</div>
<div><br>
</div>
<div>The schema is very simple, OpenSIPS exchanges SIP traffic
between another OpenSIPS (with a passthrough T38 Asterisk
behind) and a SBC, during a T38 fax call.<br>
</div>
<div><br>
</div>
<div>The sniffer on the Opensips interfaces shows that the
packets are arriving correctly.<br>
</div>
<div><br>
</div>
<div>In the capture can see the packets with red arrow are
ignored, not even writes in log, as if this packet did not
exist, it always ignores the same SIP packets, all calls are
same.<br>
</div>
<div><br>
</div>
<div>Without firewall, selinux, ip or port changes ....<br>
</div>
<div><br>
</div>
<div>A curious detail, from a moment Opensips ignores packets
from 10.201.198.60, however after BYE packet seems that it
manages SIP packets again.<br>
