Hi Oleg,
Unfortunately, at the moment there is no way to do this, as the
/add_isup_part()/ function appends an ISUP body to the SIP message
exposed in the current script route. So the only option is to add the
ISUP body to a received reply, not a locally generated one.
Also, it's not an easy/quick feature to implement, but if you don't find
a way around it and think it would be useful, please open a feature
request on Github.
Regards,

My opensips works as state-full-proxy. At the one side it works via
SIP-I, at another side via SIP. Everything is ok.
In one of my business-cases I get some INVITE with ISUP body with
certain parameters from SIP-I side I need to send 403 with ISUP body
including ISUP reason.
To do this I try to use function: send_reply("403","Some reason").
It looks like
# Encapsulate a REL
add_isup_part("REL");
$isup_param(Cause Indicators | Cause value) = 21;
send_reply("403","The reason is 21");
xlog("L_WARN","The call was rejected with 21");
exit;
But actually 403 is sending without any ISUP body.
Is it possible to do such action?
