Hi Bogdan, <div><br></div><div>I'm working with Mickael about this problem, and we have some informations which may help you (and then help us ;-) ) :</div><div><br></div><div>We have found that "loose_route" function modify the Request-URI variable ($ru), as you can see below :</div>
<div><br></div><div>ACK message comes from provider, with $ru = <a href="mailto:sip%3A%2B333XXXXXXXX@6.6.6.6">sip:+333XXXXXXXX@6.6.6.6</a></div><div>After, loose_route function is executed, and $ru become like $ru = sip:7.7.7.7;lr;r2=on;ftag=c97942d9-13c4-503ca77b-ef8c9eef-760f27a5;xyz=c12.18aedaa5</div>
<div><br></div><div>The last $ru value results from a Route header</div><div><br></div><div>For information, Record-route of previous message (200OK) is composed with two record-route in the same field, comma separated.</div>
<div>Is Opensips 1.6.4 able to interpret this type of Record-route ? </div><div><br></div><div>Is loose_route function using Route headers of previous messages (200OK before ACK) to route this message ? Or is it using only actual message's Route headers ?</div>
<div><br></div><div>Thanks in advance,</div><div>If you need further informations, feel free to ask us.</div><div><br></div><div><div>Regards,</div><div><br></div><b>Kevin MATHY</b><div><b>HEXANET</b></div><b><div><span style="font-weight:normal">--</span></div>

As the next destination should be 6.6.6.6, some stupid questions:<br>
<br>
1) is 6.6.6.6 configured in domain module or as "alias" ?<br>
<br>
2) have you check to loopback interface ? maybe the ACK is spiraling over there.<br>
<br>
Also, try to reproduce the ACK case, but enable full debug in script for the loose_route() function:<br>
if (is_method=="ACK") setdebug(6);<br>
<br>
And post the output of opensips - this will give some clue on what it is doing.<div class="im HOEnZb"><br>

The 7.7.7.7 and 8.8.8.8 IPs are both from the same instance of opensips<br>

Also, do you see any errors in the logs when the ACK is handled ?<br>

Hi,<br>
do you think this may be the cause of my routing ACK problem ?<br>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
Hi,<br>
loose route parameter lr , which can be present in sip or sips<br>
Record-Route and Route URIs to indicate that the proxy server<br>
identified<br>
by the URI supports loose routing.<br>
<br>
<br>
RFC 3261 explains the "lr" parameter as just ";lr", not lr=on. This<br>
brokes<br>
some UAs which add =on to the "lr". opensips adds=on to be<br>
compatible<br>
with these UAs<br>

Exactly Opensips add lr=on and callee device transform it into<br>
lr;r2=on.<br>
<br>
my other devices (asterisk, avaya, etc ...) do not transform lr...<br>
<br>
My Opensips version is version: opensips 1.6.4-2-tls (i386/freebsd)<br>
<br>
what is the difference between lr=on and lr;r2=on ?<br>
<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
So OpenSIPS adds "lr=on" but the callee device transform it into a<br>

Hi Mickael,<br>
<br>
Can you confirm (for the failed call) that OpenSIPS added in<br>
INVITE<br>
RR<br>
hdrs with "lr=on" param and in the 200 OK or ACK you get only "lr"<br>
param<br>
(with no value) ?<br>

Hi list,<br>
I have a routing problem with my Opensips<br>
version: opensips 1.6.4-2-tls (i386/freebsd)<br>
<br>
Indeed Opensips is unable to route ACK packet to final<br>
destination<br>
(look<br>
attachement .txt).<br>
<br>
The only difference with a normal call (Call OK), it's<br>
Record-Route<br>
formating. Customer's device send 200OK with differents fields:<br>
<br>
<br>
Test device with the problem (call NOT OK):<br>
Ex: problem call = 1 field for 2 routes<br>
