For ANI/DNIS format options 2-4 (see 3121-02: ANI/DNIS Format [Lines: Config: Setup: Caller ID Setup (3121): ANI/DNIS Format] above), use this option to set the type of data delimiter provided by the
telco. The delimiter designates the beginning and end of the ANI/DNIS data string. The delimiter can be any
character 0-9, # or *. Always set this option for compatibility with the incoming ANI/DNIS data provided by
the local telco.
