Hi Sharan, The binding cannot take place (or get refreshed or removed) when REGISTER doesn't have Contact header.
Per 3261 the registrar can either send the current binding(s) for the AoR (with remaining expiry) in 200 OK or challenge the request first and then send the binding(s) in response to the authenticated REGISTER request.
