[OpenSIPS-Users] Why is OpenSipS sending a 407

Muhammad,

 

We currently do not have cancel logic in our DP. Where should I put what you
have suggested in my DP?

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.

 

        # CANCEL processing

        if (is_method("CANCEL")) {

                if (t_check_trans()) {

                        t_relay();

                };

 

                exit;

        };

 

        t_check_trans();

 

 

Thank you.

Hi,

Our set up is this:
Client -> OpenSipS -> Custom BLF service (on port 5080).

In the DP we have:
                if ( method == "MESSAGE" || method == "NOTIFY" || method ==
"SUBSCRIBE" || method == "UNSUBSCRIBE" ) {
                        rewritehostport( "127.0.0.1:5080" );
                        route( 2 );
                        exit;

Now we have some kind of issue with our BLF service where there is a delay
on the response from it. This causes the phone to send another SUBSCRIBE.
Here is what happens.

1) Phone (SUBSCRIBE) -> OpenSips
2) Phone <- (407 with nonce) OpenSIpS
3) Phone (SUBSCRIBE WITH nonce) -> OpenSips
4) OpenSips -> Custom BLF service (port 5080)
There is no response and OpenSipS sends it again to port 5080
5) OpenSips -> Custom BLF service (port 5080)
6) Phone (SUBSCRIBE WITH same nonce as earlier) -> OpenSips
7) Phone <- (407 with NEW nonce) OpenSIpS
8) OpenSipS <- (100 trying) Custom BLF Service
9) OpenSIpS <- (200 OK) Custom BLF service
10) Phone <- (200 OK)   OpenSiPS
It seems that #9 and #10 are a result of #3. My question is why when the
phone sends the subscribe again in #6 does OpenSipS respond with a new nonce
and not to wait or something else along those lines. Yes I am using a really
old version 1.4.4.

Please see an ngrep trace below.
