There is no easy fix to come into my mind right now. But I will do

BTW, please check as you have the same routing issue also when the

<div> <tt>Hi Daniel,<br clear="none">
<br clear="none">
Actually, on the A side, you have another proxy ( see the
Record Route with 172.20.17.11 in the INVITE). OpenSIPS
tries to send the BYE to the RR header, but that is
private. A SIP proxy, if sending traffic to public
Internet, should not use at all private IPs.<br clear="none">
<br clear="none">
Bottom line, the broken link in your scenario is the </tt><tt>172.20.17.11
proxy before your opensips.<br clear="none">

<div>I'm facing an strange issue when my Opensips
instance hangs up a call, generating BYE to both sides
(timeout on dialog module or rtpproxy). The BYE is
sent to both sides but A side is behind NAT and the
BYE is sent to the local IP address and not to the
public one.</div>
