Martien,

Assuming the INVITE request is forwarded to the SP over the flow established at registration time, there would be no need to add the 'ob' parameter. Inclusion of the 'ob' parameter in the Contact header field is only for exceptional cases where there is no registration flow that can be used. The procedures of 4.3 of RFC 5626 would seem to apply.

John
