FreePBX Inbound Route not working? DDI number starts with a 2?

I spent a little while yesterday looking at an issue where a DDI number was not working on a FreePBX box. Now, I’ve set up a few trunks and inbound routes over the years so don’t normally struggle too much! but this was down to a bug (in PHP I think).

Under certain conditions the Asterisk dial plan is not written out correctly by FreePBX, causing incoming calls to fail.
