<div>Nice to hear from you again, you are always very helpful :)</div>
<div>Unfortunately, I doubt that Microsoft would listen to my
request, they're bending RFCs the way they like it, for
example - using FQDN in 'Contact' field and no 'to' tag in
this 487 reply. I assume it's quite safe to ignore this
behaviour? Thanks!</div>

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>

<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>
