You have to catch everys reply and remove the + sign.

Further you have to check all in-dialog requests received from the PSTN

client to add the + sign again.

Mmmh. In order to prevent this (which is unavoidable if you change the To: header), you might try to use P-Asserted-Identity header instead. This works with most modern SIP gateways implementing RFC3325.
