Re: [openss7] Question : ISUP in openSS7

["Brian F. G. Bidulock" <bidulock@openss7.org>]

Sandeep,

Not yet.  We have been working our way up from L2 through MTP.
There is a stub for opening an ISUP MTP-user stream head or
socket, but no ISUP state machines.  The codec code on the
website is a user-space C++ implementation of an encoder-decoder
for ISUP.

ISUP state machines tend to be far more application-specific than
the lower parts of the SS7 stack and as such are less suitable for
the OpenSS7 project which attempts to be as generic as possible
(particularly as regards national variants).

It should not be too difficult to build your own state machines
and your a welcome to use and modify the ISUP codecs to your needs.

Once the project has finished dealing with the MTP portions we
might consider going father.

There may be some other individuals on the OpenSS7 list who are
doing some open work in ISUP and there are some related projects
like Vovida (now Cisco?) and OpenH323 which have some call models
which you might consider using.  Some of the JAVA efforts might
yeild some fruit as well.

We have been focussed on a kernel MTP/SCCP implementation.  More
powerful application tools than just C programmer and better
applied to ISUP and TCAP.

I hope that we have been helpful.
