I can only comment on the BT part.

If they are two individual lines, you're out of luck with BT, as they
do not allow CLI spoofing, which this would be.

I would suggest sending BT the same number of digits that they send
you, if that doesn't work try 10 digits. If  you are not sending the
"correct" number of digits for a valid DDI on the trunk, then they
will send the lead number for the trunk.
