Summary:                    Can not change Call-Waiting tone duration and
frequency
Description: 
Our users reports that the call-waiting tone on analog phones connected to
Zaptel hardware (TDM400 & TDM2400) is too disturbing.
I tryed to change it's duration in indications.conf AND in zonedata.c
(recompiled, etc...), but it doesn't change anything (changing other tones,
ie dialtone works fine!).
Basically, whatever is configured in those 2 files, the CWT is 300ms long
at 440Hz, and is repeated every 3 or 4 seconds! (it seems that a CWT is
emitted at the beginning of each ring-back tone sent to the caller)

Another issue is that when a call is bridged between 2 local extensions,
both parties hear the CWT, so no one knows who is concerned

Here is an ugly hack that will shorten the beep, and also delay longer (in
theory) between beeps.

Note the 2400 (now 1200) - this is (simplified) beep ms * 8, and the 10000
(now 20000) at the top is the delay between beeps...in theory.

It's going to take a great deal of effort to rework how this all is
generated, and to be honest, I don't see that being done in the near term.

I think it might be appropriate to suspend this issue (and of course leave
the patch and this explanation up).  Thoughts?
