I am interested in finding information about the various call-waiting customer options that some local operating companies offer to their customers. What frequencies/durations of tones are used for this purpose? Is there more than one way to do this (from personal experience, some systems "click" and some "beep" different number of times) and are there any "standard" ways? Is there somewhere I can find this info? Thanks in advance. I'll post a summary when I get responses.
