[asterisk-users] trouble removing + sign

I'm using BLACKLIST() to check numbers, which does not like leading + 
signs. I want to test if there is a plus sign, and then remove it.

I tried:

  ;  strip leading plus sign
   same => n, Verbose( callerid 0:1 is ${CALLERID(num):0:1} )
   same => n,ExecIf($["${CALLERID(num):0:1}" = "+"]?Set(CALLERID(num) = 

but it's stripping the first character + sign or not. The callerid is 

     -- Executing [s at hangup-spam:3] Verbose("PJSIP/2667075-0000000b", " 
callerid 0:1 is 1 ") in new stack
  callerid 0:1 is 1
     -- Executing [s at hangup-spam:4] ExecIf("PJSIP/2667075-0000000b", 
"0?Set(CALLERID(num) = 203XXXYYYY") in new stack
     -- Executing [s at hangup-spam:5] GotoIf("PJSIP/2667075-0000000b", 
"0?make-em-wait") in new stack

ExecIf correctly finds the comparison false(the "0"), but still executes 
the appiftrue .

What am I missing ?
