[OpenSER-Users] scope of openser flags

[Hugo Koblmueller]

high.bogdan!

well i wasn't aware of that, thanks. :)
so i applied a reply ID and added the t_on_reply() function, but i still
have the same problem - the flags are not set in the reply route?
see ...

route {
...
    if (src_ip == 172.xx.xx.xx) {
#       relay request to *
        if (!t_relay("udp:172.xx.xx.xx:5060")) {
            sl_reply_error();
        }
    }
    else {
#       relay request to OCS
        if (!t_relay("tcp:172.xx.xx.xx:5060")) {
            sl_reply_error();
        }
    }

#   use a non-generic reply route to be able to use transaction flags
    t_on_reply("1");

    if (method == INVITE) setflag(3);
    xlog("L_INFO","$Cyb$rm: mf=$mf, bf=$bf, sf=$sf$Cxx\n");
    exit;
}
 
onreply_route[1] {
    xlog("L_INFO","$Cyr$rs($rr): mf=$mf, bf=$bf, sf=$sf$Cxx\n"); }


still get the output:
10(11658) INVITE: mf=8, bf=0, sf=0
 5(11653) 100(Trying): mf=0, bf=0, sf=0
 7(11655) 180(Ringing): mf=0, bf=0, sf=0
 8(11656) 200(OK): mf=0, bf=0, sf=0
10(11658) ACK: mf=0, bf=0, sf=0
 6(11654) BYE: mf=0, bf=0, sf=0
11(11659) 200(OK): mf=0, bf=0, sf=0

any ideas on that?

thx & cheers

Hi Hugo,

The flags you mention are per transaction flags and they are visible as time
the route is in a transaction context. Unfortunately you came across the
only exception. You are using the generic "onreply_route"
where there is no transaction contect (openser has no idea -yet- about the
transaction the reply belongs to). A reply route with transaction context is
onreply_route[x] - this is set per transaction by t_on_reply().

Regards,
Bogdan
