<div dir="ltr">Hi Vlad,<br>
Thankyou for response<br>
I'm saying that i need to remove the ISUP not only in INVITE method, but in the whole dialog <br>
now i have in script
<div>route {</div>
<div> if (has_totag()) {<br>
# sequential requests within a dialog should<br>
# take the path determined by record-routing<br>
if ($si=="10.10.20.20") {<br>
xlog ("Removing ISUP body part in sequential requests to host which dont want it...\n");<br>
remove_body_part("application/isup");<br>
}<br>
}<br>
if (is_method("INVITE") && ($si=="10.10.20.20") ) {<br>
xlog ("Routing INVITE \n");<br>
# telecom trunk - outbound calls<br>
rewritehostport("195.***.***.66:5060");<br>
# Do cut SIP-T, here it working<br>
remove_body_part("application/isup");<br>
xlog ("And activate topology hiding B2B\n");<br>
b2b_init_request("top hiding");<br>
exit; #do not forward this request, another on will be generated<br>
<br>
}<br>
</div>
<div><br>
</div>
<div>}</div>
<div><br>
</div>
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.

<p>Hi Alexey,</p>
<p>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 ?</p>
<p>Regards,<br>

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

</div>
<div>Thanks.</div>
