<tt>Hi, Royee!<br>
<br>
As you can see in the logs, the route set is shrikend - so
opensips cannot restore the entire information.<br>
Taking a look at the trace you have sent, it is clear that the
client is not sending the second SUBSCRIBE with all the
information:<br>
* The 200 OK thinfo param has 154 chars<br>
* The SUBSCRIBE thinfo has only 55 chars<br>
<br>
I would check whyt the client is not using the entire thinfo
param.<br>
<br>
Best regards,<br>
</tt>

<div dir="ltr">Hi,
<div><br>
</div>
<div>I am using opensips 2.1 and I'm experiencing some weird
behavior with SUBSCRIBE handling on an opensips server
that is behaving as a SIP proxy. I also use the
topology_hiding module to hide routing information from
the clients.</div>
<div><br>
</div>
<div>The proxy receives an initial SUBSCRIBE from a device,
the SUBSCRIBE doesn't contain a "to tag" so I process it
like a normal SUBSCRIBE message and route it to the
correct route which replies with a 200 OK with a "to tag".
Some time before the expiration of the SUBSCRIBE is passed
I receive a another SUBSCRIBE, this time with a "to tag"
so my opensips config file attempts to match it to a
topology matching but for some reason it fails to match
it.</div>
<div><br>
</div>
<div>I have this configured:</div>
<div>
<pre style="font-family:Menlo;font-size:9pt">modparam("dialog", "dlg_match_mode", 0)</pre>
<pre style="font-family:Menlo;font-size:9pt">
</pre>
<pre style="font-family:Menlo;font-size:9pt">Any idea why the second subscribe message is not being matched?</pre>
<pre style="font-family:Menlo;font-size:9pt">
</pre>
<pre style="font-family:Menlo;font-size:9pt">Attached is a capture of the initial and following subscribes.</pre>
<pre style="font-family:Menlo;font-size:9pt">
