You need to use t_check_trans(); right after CANCEL processing, this will absorb re-transmission of SUBSCRIBE or whatever method that may be, e.g.<div><br></div><div><div>        # CANCEL processing</div><div>        if (is_method(&quot;CANCEL&quot;)) {</div>

<div>                if (t_check_trans()) {</div><div>                        t_relay();</div><div>                };</div><div><br></div><div>                exit;</div><div>        };</div><div><br></div><div>        t_check_trans();</div>

<br>
Our set up is this:<br>
Client -&gt; OpenSipS -&gt; Custom BLF service (on port 5080).<br>
<br>
In the DP we have:<br>
                if ( method == &quot;MESSAGE&quot; || method == &quot;NOTIFY&quot; || method ==<br>
&quot;SUBSCRIBE&quot; || method == &quot;UNSUBSCRIBE&quot; ) {<br>
                        rewritehostport( &quot;<a href="http://127.0.0.1:5080" target="_blank">127.0.0.1:5080</a>&quot; );<br>
                        route( 2 );<br>
                        exit;<br>
<br>
Now we have some kind of issue with our BLF service where there is a delay<br>
on the response from it. This causes the phone to send another SUBSCRIBE.<br>
Here is what happens.<br>
<br>
1) Phone (SUBSCRIBE) -&gt; OpenSips<br>
2) Phone &lt;- (407 with nonce) OpenSIpS<br>
3) Phone (SUBSCRIBE WITH nonce) -&gt; OpenSips<br>
4) OpenSips -&gt; Custom BLF service (port 5080)<br>
There is no response and OpenSipS sends it again to port 5080<br>
5) OpenSips -&gt; Custom BLF service (port 5080)<br>
6) Phone (SUBSCRIBE WITH same nonce as earlier) -&gt; OpenSips<br>
7) Phone &lt;- (407 with NEW nonce) OpenSIpS<br>
8) OpenSipS &lt;- (100 trying) Custom BLF Service<br>
9) OpenSIpS &lt;- (200 OK) Custom BLF service<br>
10) Phone &lt;- (200 OK)   OpenSiPS<br>
It seems that #9 and #10 are a result of #3. My question is why when the<br>
phone sends the subscribe again in #6 does OpenSipS respond with a new nonce<br>
and not to wait or something else along those lines. Yes I am using a really<br>
old version 1.4.4.<br>
<br>
Please see an ngrep trace below.<br>
