I think what C F was trying to get at is:

1) When you post a question it helps very much if you are as specific
as possible.  Provide as many details as you can.  From your original
post, it was very unclear what you were getting at.

2) Read.  Don't be lazy.  Take the time to learn.  Don't expect
somebody else on the list to spoon feed you answers.  Nobody is paid to
read this list, and most people will appreciate you putting in a little
effort.  Somebody probably will give you the answers eventually, but
you'll get the answer a lot faster if you've shown that you tried to
find the answer yourself first.

Now, to answer your question - *70 is a feature available from many
standard phone providers.  You can use it to tell your provider to turn
off call waiting.  If you never want call waiting, it might be a good
idea to have the phone company disable it (you might save some money).
If you can't do that, or you still want it sometimes, you can tell
asterisk to just ignore call waiting.  To do so, it would depend on
what kind of incoming connection you are using.  If it is a Zap line,
you can disable call waiting in zapata.conf (callwaiting=no).  If it is
an iax or sip connection, it's probably easiest tell your provider to
turn it off, though there are ways to do it in the dialplan if this is
not possible.  I don't know about the other connection types.

I hope this helps,
Noah
