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>
$var(isup) = "\x06\x12\x25\x01\x39\x02\x12\<wbr>x01\x00";<br>
append_body_part("$var(isup)",<wbr>"application/isup;version=itu-<wbr>t92+","signal;handling=<wbr>optional");<br>
msg_apply_changes();<br>
$avp(s:xxxx) = $rb;<br>
$var(xxxx) = $(avp(s:xxxx){re.subst,/(.*)--<wbr>unique-boundary-1(.*)/\1--<wbr>unique-boundary-1--\2/sg});<br>
set_body("$var(xxxx)","<wbr>multipart/mixed;boundary=\"<wbr>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" target="_blank">https://github.com/kamailio/<wbr>kamailio/blob/master/modules/<wbr>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.
