Hi Jorge,<br>
<br>
So opensips tries to send the BYE to Z.Z.Z.Z:5062 via TCP (guess
based on Route hdrs), but nobody is listening on TCP - is this
address pointing behind a NAT ? why is not accepting a new TCP
connection.<br>
<br>
On the other side, what you can do is to reduce the timeout on TCP
connection, so opensips will react sooner:<br>

Hi Bogdan,<br>
<br>
Exactly, is ready, OpenSIPS try to reach to destination but now
the account 2105 haven't the location: Z.Z.Z.Z:5062<br>
<br>
In fact, when OpenSIPS try to reach to there, it write in
log: (this account uses TLS signaling)<br>

Subject: Re: [OpenSIPS-Users] sip message enters on bucle<br>
<br>
Hi Jorge,<br>
<br>
It looks like Asterisk generates the BYEs and retransmits it
because there is no reply coming back from opensips. Normally
the BYE is end 2 end replied (so the other end device should
generate the reply for BYE).<br>
But looking at the 477 reply you get from OpenSIPS, I suspect
that OpenSIPS was trying to forward the BYE request (maybe via
TCP), got blocked and failed at the end - this failure
resulted in the 477 reply.<br>
<br>
Check the opensips logs to see error when processing the BYE.<br>
<br>
Regards,<br>
Bogdan<br>
