Hi Alexey,
I did this with t_on_reply(). Something like this:
route {
if (has_totag()) {
# sequential requests within a dialog should
# take the path determined by record-routing
if ($si=="10.10.20.20") {
xlog ("Removing ISUP body part in sequential requests
to host which dont want it...\n");
remove_body_part("application/isup");
t_on_reply("reply_normal_sip_leg");
}
}
if (is_method("INVITE") && ($si=="10.10.20.20") ) {
xlog ("Routing INVITE \n");
# telecom trunk - outbound calls
rewritehostport("195.***.***.66:5060");
# Do cut SIP-T, here it working
remove_body_part("application/isup");
xlog ("And activate topology hiding B2B\n");
b2b_init_request("top hiding");
exit; #do not forward this request, another on will be generated
}
}
onreply_route[reply_normal_sip_leg] {
remove_body_part("application/isup");
}

Aihe: Re: [OpenSIPS-Users] Removing ISUP part from sip dialog
Hi Vlad,
Thankyou for response
I'm saying that i need to remove the ISUP not only in INVITE method, but in the
whole dialog
now i have in script
route {
if (has_totag()) {
# sequential requests within a dialog should
# take the path determined by record-routing
if ($si=="10.10.20.20") {
xlog ("Removing ISUP body part in sequential requests
to host which dont want it...\n");
remove_body_part("application/isup");
}
}
if (is_method("INVITE") && ($si=="10.10.20.20") ) {
xlog ("Routing INVITE \n");
# telecom trunk - outbound calls
rewritehostport("195.***.***.66:5060");
# Do cut SIP-T, here it working
remove_body_part("application/isup");
xlog ("And activate topology hiding B2B\n");
b2b_init_request("top hiding");
exit; #do not forward this request, another on will be generated
}
}
This code removes the ISUP part from the INVITE request, from 10.10.20.20 to
the upper trunk but when I receive the 180 ringing signal with the ISUP part I
need to remove it too.
Regards, Alexey.

Hi Alexey,
The remove_body_part() function should work for any method and replies as well.
So are you saying that you have actually tried the function and it has no
effect ?

good day.
Could anybody advise me if it is possible to remove ISUP part from whole SIP
dialogue
Now I have only found that there is no problem to remove it from the common
methods
like
if (is_method("INVITE") ) {
remove_body_part("application/isup");
}
but i see ISUP part in the 180 or 186 messages or in the BYE method
Thanks.
