Not sure from your description of the numbers whether you are referring
to the dialling rules in FreePBX or to what happens between the dialplan
and the PRI. What I am about to say is applicable to the latter,
ignoring whatever FreePBX does.

I believe there are two possibilities:

1. Use pridialplan=unknown, leave nationalprefix and internationalprefix
   both empty, and give the full number to Dial(), as you would dial it,
   i.e. 020xxxxxxxx, 07xxxxxxxxx, 00x[whatever]
   The numbers will be sent over the PRI as TON unknown, without stripping
   any digits.

2. Use pridialplan=dynamic, nationalprefix=0, internationalprefix=00, and
   still give the full number to Dial(). In this case, the dynamic setting
   will match a leading 00, strip it and set TON=International, or else
   match a leading 0, strip it and set TON=National, or else it will
   set TON=Local and not strip any digits.

In both cases, make sure your FreePBX dialling rules are set NOT to strip
the 0 or 00 prefixes.

Actually, I think if pridialplan is NOT dynamic, the national and
international prefixes are ignored for dialling, but can still be usefully
set to 0 and 00 to get incoming CallerId into the correct format.

Cheers
Tony
