Caller ID Call Routing The VPS automatically sends calls from pre-
assigned CLIP numbers to the desired extension,
mailbox, or Custom Service. Custom Service is
especially useful in a country where several
languages are used, because Custom Service
menus can be recorded in any language.
Personal Greeting for Caller ID Each subscriber can record up to 4 personal
greeting messages for special callers.
