Call by name doesn't match 2 character length names. If there was a wildcard or filler digit I could match names like YU, LI etc. I could change the CALLBYNAME_MINLEN to 2 but then I'd get more matches and need to record another system prompt. With a wildcard 98* could match YU or YUNG. If its a filler digit 98* would only match to YU. According to support CALLBYNAME_MAXLEN is depreciated in v15.
