Oracle SBC - How to change 00 to +

Hello Everyone,

I'm having a hard time with manipulation of International Codes.
In a scenario where a call is destined to 0033 04 51 08 XX XX, where I must match the "00" and swap it for the "+".
The issue I'm facing is how can I store everything that follow the "00" and add it back with the "+" sign.

Or, to be clearer: How can I strip the first two digits from the DDI and prepend the + sign?

Regards,

Jorge Grave.
