If a call comes in from a PSTN (POTS) line into a PSTN<-->SIP gateway, the PSTN line MAY provide Calling Party ID, if that functionality is enabled at the exchange, but it WILL NOT provide Called Party ID as there is no standard for providing such information through a standard POTS line. If that information cannot be provided to the gateway through the PSTN interface, then the gateway will be unable to provide such information in the "To:" field of the SIP INVITE.
The only way to get that info in there would be to set the gateway up to manipulate the "To:" field according to which FXO line the call came in on, but if you're going to do that, then you might as well just manipulate the "To:" field to point to the extension number that you wish to receive incoming calls.
