color=#0000ff size=2>I've done some SS7 development in the past, using dedicated
TX3220 and TX4000 signalling boards from NMS Communications (recentlty aquired
by Dialogic). Even with a lot of commercial documentation available, it's
horribly complex stuff, especially redundancy. And you need another SS7 switch
to test against for interoperability. And SIP trunks are becoming more and more
commonly available these days, so one can question if it's worth the effort.
Still, I would really like it if someone would try and develop such a
feature.</FONT></SPAN></DIV>

other SS7 switches.</FONT></SPAN></DIV>

<DIV></DIV>Trust me AT&T doesn't have free docs. There are hundreds of ANSI
SS7 docs and they put alot of work and money to make sure you can't get them via
google search. Much of it is not in ITU but many ITU switch support ANSI
features such as Class 5. Even with the ITU docs in hand you'll need a
large team to get it complete enough for Class 4/5 operations anytime soon.<BR>

the same thing we saw... Everyone wants SS7 but no one wants to help
fund it... And to make matters worse just getting proper documentation for
ANSI SS7 is not exactly a cheap endeavor. Unfortunately telecordia and crew
still want to charge thousands of dollars for the docs when the ITU decided
ages ago to make those available for free... Even then its still a substantial
amount of effort to get something working (even if you have active links you
can use to help understand whats going on)<BR><BR>K<BR><BR><BR><BR><BR>
