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

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:
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();
}
}
if (method == INVITE) setsflag(3);
xlog("L_INFO","$Cyb$rm: mf=$mf, bf=$bf, sf=$sf$Cxx\n");
exit;
}
onreply_route {
xlog("L_INFO","$Cyr$rs($rr): mf=$mf, bf=$bf, sf=$sf$Cxx\n");
}
the output is the following:
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
