[VoIP] Call progress sounds

[ikjtel]

Three things...

1. It does seem to be somewhat version dependent,
unfortunately.  Also, please note that the page at
ckts.info, which Greg was kind enough to create,
mentions a file download named 'sf.patch' - there were
problems (Jon K if I recall correctly) with this
version so a newer version was released named
'sf2.patch'.  See also the following link
http://www.lightlink.com/mhp/sf/sf.txt

2. It would probably actually be quite easy to add
code to hear the dial pulses with attenuation (the
exact amount might need to be determined
experimentally).  Apparently my eardrums must be more
cast-iron than JN's, since that never bothered me.

3. However what really did bother me was the SxS
selector "clunk" sound (the D relay operating to cut
thru after the digit) was getting suppressed by the
X100P hardware.  After all, that particular sound is
the one reason why we all have SxS selectors, no?  :-)
 I am hoping that channel bank FXO rather than X100P
(or TDM400P) FXO may fix this "problem" , but don't
have the equipment here to test*.  A separate but
related problem was that * doesn't leave very much
interdigital time (by default), so the next following
digit is starting before you've had time to realize
it...

* JN - would you be interested in pursuing?  Did you
say that you had a channel-bank FXO?
