When you've got an * in the Contact header and an Expires of 0 it
means that the registrar server has to delete all contacts for the AoR
present in the To:
I guess you would have to identify whether the incoming REGISTER is
provinding a binding (Expires>0) or removing it (Expires=0) to act
appropriately.
The use of * is "perfectly" defined in RFC 3261.
Remember that the expiration interval can either be in a single
Expires header or as a header parameter in the Contact header.....

Hi
I want to overwrite the contact header field using textops but some UAs send
only an asterisk as a contact (like below). Is this defined in protocol (I
didn't find) ? I don't decide what to do . Do I reply with an error or use
another field (from,to) as contact
thanks
