Default International calls failing

Same basic question.
International Calls won't go through on my new IP500 V2 8.1 with PRI
My ISP says that the Numbering Plan (NP) is coming out as "unknown" but they need it to come out as ISDN Telephony E.164. Noone seems to know how to make that happen.

Any help appreciated.
Pat.
