<tt>Hi Yury,<br>
<br>
No need to call any script function - all you need to do is to
point your carrier to read the RFC3261 -> any final SIP reply
MUST have a TO-tag.<br>
<br>

<div dir="ltr">Hi,
<div>My upstream carrier is replying back to CANCEL request with
a 487 Call Cancelled message that doesn't have a 'to' tag in
its headers. So, I'm getting these errors in OpenSIPS logs:<br>
<br>
</div>
<div>ERROR:dialog:push_reply_in_dialog: [487] reply in dlg state
[2]: missing TAG param in TO hdr<br>
</div>
<div><br>
</div>
<div>But dialogs are closing correctly on BYE and I don't see
any dialogs hanging in any state when the call is finished. Is
it something I should be worried about or can I just ignore
this error? Is there any way to avoid it by OpenSIPS script
processing logic? Maybe I need to call some function to fix
this dialog? Thanks!</div>
