asterisk users - Sep 2006 - How to manipulate a plus in a phone number

I'm hoping someone has solved this problem before, because I'm stuck!

I get phone numbers from a database into my dial plan via AGI.
Some of the numbers use the + sign to denote an 'international'
number.
I need to re-write these numbers into a format my IAX provider
can deal with (ie a us style international number starting with 011).

So +3115162728 -> 00113115162728

Unfortunately all the ways I've tried to manipulate the number
in the dialplan fail because the + is an operator and I can't get
the parser to treat it as a 'normal' string.
Here are some things I have tried to use to detect the +

exten => 1,n,set(INNAT=${ATELNO:\+})

and

exten => 1,n,set(INNAT=${REGEX("^\+","${ATELNO}")})

and

exten => 1,n,set(INNAT=${FIELDQTY(+,${ATELNO})})

None of them work.....

I know I could get the database to do the rewriting, but then
I've got database code that is IAX provider dependent, which I'd like  
to avoid.

Anyone got any neat tricks??

Just a grab in the dark, have you tried using single quotes instead of 
the double?

If it is an extension, this should work too

exten => _+.,1,Goto(011${EXTEN:1},1)

That worked, Thanks!

This is what I do:
exten => s,n,gotoif($["${EXTEN:0:2}" =
"+1"]?fixcid:okcid)
exten => s,n(fixcid), set(xxx=${EXTEN:0:2})
exten => s,n(okcid), noop()
