Dial Patterns

Hello all.

I have some problems with setting my cell phone to dial out.

The problem are that mobilephone add + and landcode. Like +45xxxxxxxx.

I have make a rule:
+45|.
And it is working.

Great, but I can not call interantional call from my cell phone.

I want a rule to replace + with 00.
I have tried:
+|00+.
And I have tried:
+1|001+.

But nothing of are working.
I using trixbox 2.6.1 with freepbx 2.4.0

Please advice
