You should get away with

exten => _+[1-9].,1,Goto(00${EXTEN:1},1)

If you had any special use for triple-0 numbers (as we do), you should
afaik also be able to use

exten => _+.,1,Goto(00${EXTEN:1},1)

We do not allow "+0" numbers though because that would contradict the
meaning of a "000" number in our setup. Generally "+AABBBCCC" is dialled
as "00AABBBCCC", as international phone call, through our outward phone
provider without them noticing any weird + signs.
