So correct me if I'm wrong but in a previous mail you said that
sending multiple REGISTER with unique Contact works even using
Outbound. Could I know how those REGISTER's Contact headers look? (it
would be useful to see two of them).

I would like to understand why the registrar stores different bindings
when the sip.instance and reg-id are the same. It's not clear for me.
