[Freeswitch-dev] FreeSWITCH SS7 stack

Wed Jan 28 12:47:16 PST 2009

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.

Off-topic: If you need SS7 and are willing to pay for it, I can
recommend audiocodes mediant gateways. There's a model available with
embedded SS7 signalling, provided by Teles. And real cheap too, compared
to other SS7 switches.

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.

	Next time try to search if AT&T have a free version of the doc
first - you might get a suprice.

	Must be nice ;) 

	Here in the states they want you to pay for documentation on
cable pinouts and don't even think about getting documentation for
something like TCAP LIDB without giving up your first born and an arm.

	I live in Europe - and ITU/ETSI are free :)

	That's 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)

	This is a little like the hen and the egg...

	No one will support you starting to write a SS7 ++ stack, but
once you get going and the first stacks turns up, so will business.

	I still see a compelling business case for a foundation
supported free open source set of libs for the base protocols,
commercially supported by multiple contributors who build higher level
applications using the base protocols.  In a situation like this,
commercial sponsors can pool resources for certification.  Obviously
anyone using a modified version would not be using certified code but
the sponsors who pay for certification would still get multiple
benefits.

		I don't see a non Commercial one getting certification
and then getting widely used here in the states... That's the problem
you have to spend tons of time to get them certified... Its not like SIP
where they will pretty much take anything and everything unfortunately

		We should have an open source one too thats MPL or BSD
... I don't agree with selling protocols like this commercially.  Guess
thats just the Open Source in me wanting that stuff to be free.

			There are things available for this in the
commercial space.  One from CometSig.com and one from sangoma.  Nothing
at this time in the opensource arena. (OpenSS7 will not be integrated
with freeswitch due to licensing issues)

			Contact me off list if you are interested in
either of the commercial versions I can assist you with these things.
