Here is a simple way to strip the '-' 

Here is a concept solution.
I have not tested the code so there may be some syntax errors. 
It can work as I am doing stuff like this all the time. This example is 
using a check to only do the cut if there is more than one field. You may 
be able to just use step 3 from ctx and have what you want, but I am not 
sure if it will fall back gracefully if there is only 1 field. 

No AGI required.

exten => mycode,n,Gosub(ctx,1)

exten => ctx,1,Set(l_filedCNT=${FIELDQTY(CALLERID(num),-)})
exten => ctx,n,GotoIf($[${MATH(${l_filedCNT}>1)}=TRUE]?DoStrip:doSkip)
exten => ctx,n(doStrip),Set (CALLERID(num)=${CUT(CALLERID(num), -, 1-)})
exten => ctx,n(doSkip),NoOp(${CALLERID(num)})

Thanks

Made a correct in the above to reflect the skip state doSkip vs SkpStrip 
and made syntax correct to the Set/CUT line. There may still be a few more 
syntax issues in there.
