All outgoing initial SIP requests are forwarded to an Application Server (AS) providing the TIR simulation service under the following conditions:

– The originating user does not subscribe to the TIP service and the AS removes the P-Asserted‑Identity header fields and the Privacy header field.

NOTE: Responses follow the same route as requests, so the responses will also be routed via the AS.
