Well, it is rather sparce, but probably what any one would need.
Here's the deal:
Primary Announcement answers, gives a message and then hangs up, putting caller on hold.
After a period of time (Specified in the CG Setup) Secondary announcement says it's thing.
Then, after a delay, secondary announcement does it's thing again, and again and again.... UNTIL and UNLESS it's set to TIME OUT and go elsewhere.
AND/OR you can set up a PROMPT OUT OF ANNOUNCEMENT option, where as the SECONDARY Announcement says:
" to get out of this endless loop, press the POUND SIGN"
Then your caller is sent to the OVERFLOW place.
I hope this helps.
OF COURSE, this has to be R6.1 or 7.0 (I Think) 5.0 May have done it, but I ONLY deal with 7.0 or later, other wise, I upgrade to 7.0.
