Description:The asterisk format for creating substrings ${VAR:1:2} works perfectly with static figures, but does not accept variable offsets, for instance:


What happens in this case, where VAR=123 and LEN=1 is an evaluation to "1231" rather than "12" - a string with a single character removed from the back.

Possible workaround in dialplans would be an asterisk SUBSTR() function, but this does not exist.

Seems to work fine for me:

   -- Executing [123@test:1] Set("Local/123@test-3d26,2", "VAR=123") in new stack
   -- Executing [123@test:2] Set("Local/123@test-3d26,2", "LEN=1") in new stack
   -- Executing [123@test:3] NoOp("Local/123@test-3d26,2", "12") in new stack
