high.*!

i'm using openser v1.2 and am a bit confused about the scope of the flag. just for information about my setup: i use openser as gateway between OCSmediation server and asterisk.

i learned that the message flags are transaction persistent, which means that if i set some flags while processing the INVITE request, these flags must be visible also when we process all other requests and replies in scope of the same transaction.

and i also learned, that the flags which are set for INVITE are visible only when processing 100 (Trying), 180 (Ringing), and 487 (Request Cancelled). however, the flags are not visible when processing CANCEL, 200 (OK), and ACK.
thats for the theory.

now i have two problems:
first (as i mentioned above) i experienced, that 'my' flags are not that visible as they should be. means e.g. i set flag 3 in request route and print it out in onreply_route, where it seems not to be set.
see my code below:

    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();
        }
    }
    if (method == INVITE) setsflag(3);
    xlog("L_INFO","$Cyb$rm: mf=$mf, bf=$bf, sf=$sf$Cxx\n");
    exit;
}

10(10569) INVITE: mf=0, bf=0, sf=8
7(10566) 100(Trying): mf=0, bf=0, sf=0
5(10564) 180(Ringing): mf=0, bf=0, sf=0
8(10567) 200(OK): mf=0, bf=0, sf=0
10(10569) ACK: mf=0, bf=0, sf=0
6(10565) BYE: mf=0, bf=0, sf=0
11(10570) 200(OK): mf=0, bf=0, sf=0

as you can see the flag 3 is only set, while processing the INVITE but after this is stays reset.

any ideas which problem i'm facing here?

my second problem is, that i need to identify the reply "200 OK" which is answered to the relayed INVITE message. as i mentioned above, this will not be covered by the flags scope anyways. Sad

is there any possibility to have kind of (real) global variables in openser.cfg?

thx & cheers
