hello Sergey
yes i was using them with a IAM ISUP part inside the SIP response, so
they were doing something, but it's not correct so it must be an ACM,
ANM depending on the response.
i made some more tests and i saw the issue is not with append_body_part
which seems it's doing ok.
it's with set_body_multipart when in responses seems cannot detect the
body last boundary and close it by -- so the ISUP is malformed
i could workaround this by parsing the body and adding it
route[SIPISUP] {
msg_apply_changes();
set_body_multipart();
msg_apply_changes();
$var(isup) = "\x06\x12\x25\x01\x39\x02\x12\x01\x00";
append_body_part("$var(isup)","application/isup;version=itu-t92
+","signal;handling=optional");
msg_apply_changes();
$avp(s:xxxx) = $rb;
$var(xxxx) =
$(avp(s:xxxx){re.subst,/(.*)--unique-boundary-1(.*)/\1--unique-boundary-1--\2/sg});
set_body("$var(xxxx)","multipart/mixed;boundary=\"unique-boundary-1
\"");
}
this way at least we have a base ISUP part for a 1XX response
best regards

Hi David,
if you look at source code of the sipt module
https://github.com/kamailio/kamailio/blob/master/modules/sipt/sipt.c
functions sipt_destination & sipt_set_calling works only for ISUP_IAM.
But as I know from my tests ISUP encapsulation must be only in invite,
and is optional for other messages.

hello all
i'm using kam version 4.4.1 and i would like to generate an ISUP part on the
1xx,2xx responses to a remote carrier since the fsw i send the calls to
cannot handle ISUP SDP.
despite seeing in the doc that those functions cannot be used there and only
in REQUEST_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE, i tried and it works....
partially, because it seems it doesnt create the last boundary and it
creates a next boundary with an empty "Encapsulated multipart part: "
this the the route i call from onreply_route
route[SIPISUP] {
set_body_multipart();
msg_apply_changes();
$var(isup) =
"\x01\x12\x49\x01\x0a\x03\x02\x0a\x08\x84\x90\x33\x41\x72\x17\x01\x06\x0a\x08\x04\x13\x93\x70\x21\x73\x23\x10\x08\x01\x01\x00";
append_body_part("$var(isup)","application/isup;version=itu-t92+","signal;handling=optional");
msg_apply_changes();
sipt_destination($rU, 31, 4);
sipt_set_calling($fU, 4, 0, 3);
msg_apply_changes();
}
am i doing something wrong? how can i set this to end the SDP with last
boundary?
thanks a lot and regards
david
