The answers aren't set by the SIP standards. However, given that the SIM gives the Directory Number of a PSTN telephone, I would expect that if you change the SIM on a UE, the UE would register for the new DN. In SIP, the From address in an INVITE is not necessarily connected with any AOR that the UE registers for. But in a PSTN telephone, I would expect it to use the SIM's DN as the From URI.
