<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Hi,<br>
<br>
Our set up is this:<br>
Client -> OpenSipS -> Custom BLF service (on port 5080).<br>
<br>
In the DP we have:<br>
if ( method ==
"MESSAGE" || method == "NOTIFY" || method ==<br>
"SUBSCRIBE" || method == "UNSUBSCRIBE" ) {<br>
rewritehostport( "<a href="http://127.0.0.1:5080" target="_blank">127.0.0.1:5080</a>"
);<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) -> OpenSips<br>
2) Phone <- (407 with nonce) OpenSIpS<br>
3) Phone (SUBSCRIBE WITH nonce) -> OpenSips<br>
4) OpenSips -> Custom BLF service (port 5080)<br>
There is no response and OpenSipS sends it again to port 5080<br>
5) OpenSips -> Custom BLF service (port 5080)<br>
6) Phone (SUBSCRIBE WITH same nonce as earlier) -> OpenSips<br>
7) Phone <- (407 with NEW nonce) OpenSIpS<br>
8) OpenSipS <- (100 trying) Custom BLF Service<br>
9) OpenSIpS <- (200 OK) Custom BLF service<br>
10) Phone <- (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>
