[SR-Users] set_body_multipart and append_body_part

I made it work but I have to set multipart always in request route (as the
manual says) to apply the changes. Just a comment. If I don't apply changes
after append_body_part, kamailio crashes.
if (is_method("INVITE") && !has_totag()) {
set_body_multipart();
msg_apply_changes();
$var(gtd) =
"IAM,\r\nCPC,"+$avp("ch")+"\r\nGCI,asdfasd\r\n\r\n";
append_body_part("$var(gtd)", "application/gtd",
"signal;handling=optional");
msg_apply_changes();
}
I know that this is the way as it works (just apply changes in request
route) but with rtjson and the evapi module I decide if it has to have or
not multipart later and not in the first invite.
Is It possible to add in new versions of kamailio to apply the changes in
branch route too? (this would be a new request)
Cheers.
Diego.
