asterisk users - Jul 2004 - How to handle a macro that dials both international (011) and national

I have a macro that handles my outbound dialing...  First it does an enum 
lookup, and if that fails it hands the call off to voicepulse for connection.

The problem is... EnumLookup() requires that international numbers *NOT* be 
prefixed with 011, however VoicePulse does...     Can someone provide me with 
a suggestion as to how I can accomplish this without TWO macros?  (one for 
national, one for international)

Thanks!
