Yeah, just ignore it, anyhow there is nothing we can do about it.

Hi Bogdan,
Nice to hear from you again, you are always very helpful :)
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!
Regards,
Yury.

Hi Yury,
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.

Hi,
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:
ERROR:dialog:push_reply_in_dialog: [487] reply in dlg state [2]:
missing TAG param in TO hdr
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!
Regards,
Yury.
