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.
