hello Sergey<BR>
<BR>
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.<BR>
i made some more tests and i saw the issue is not with append_body_part which seems it's doing ok.<BR>
<BR>
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<BR>
<BR>
i could workaround this by parsing the body and adding it <BR>
<BR>
route[SIPISUP] {<BR>
msg_apply_changes();<BR>
set_body_multipart();<BR>
msg_apply_changes();<BR>
$var(isup) = "\x06\x12\x25\x01\x39\x02\x12\x01\x00";<BR>
append_body_part("$var(isup)","application/isup;version=itu-t92+","signal;handling=optional");<BR>
msg_apply_changes();<BR>
$avp(s:xxxx) = $rb;<BR>
$var(xxxx) = $(avp(s:xxxx){re.subst,/(.*)--unique-boundary-1(.*)/\1--unique-boundary-1--\2/sg});<BR>
set_body("$var(xxxx)","multipart/mixed;boundary=\"unique-boundary-1\"");<BR>
}<BR>
<BR>
this way at least we have a base ISUP part for a 1XX response <BR>
<BR>
best regards<BR>

Hi David,
if you look at source code of the sipt module
<A HREF="https://github.com/kamailio/kamailio/blob/master/modules/sipt/sipt.c">https://github.com/kamailio/kamailio/blob/master/modules/sipt/sipt.c</A>
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.
