Matthew Fredrickson has posted details of a new SS7 implementation:
Hey all! For the past year I have been working on and off on an SS7 implementation here at Digium called libss7. I have it to the point where it can pass phone calls, so I figured it would be a good time to release it and let people begin testing it. It's still somewhat "bare bones" in functionality, but I've been doing a lot of fleshing out of the implementation.
Currently, it has been used (making and receiving phone calls) and developed in an ITU SS7 environment, but I have a good chunk of the code included which is required for ANSI support as well. I think I'm going to get an ANSI link in a few weeks, so hopefully I'll have that tested and working relatively soon.
It supports MTP2, MTP3, and ISUP. After I get these layers fleshed out, I'm planning on starting on SCCP and the layers above that with the eventual goal of database-lookup and SMS support.
To test, you must have a T1/E1 card as well as an SS7 link. You also need to have zaptel installed on your system.
Here are the instructions for checking it out of subversion and getting it working:
`svn co http://svn.digium.com/svn/libss7/trunk libss7`
`cd libss7`
`make install`
Right now, the changes to chan_zap are implemented in a special developer branch of asterisk. These are the instructions to check it out
`svn co http://svn.digium.com/svn/asterisk/team/mattf/asterisk-ss7 asterisk-ss7`
`cd asterisk-ss7`
If you haven't compiled trunk yet, you may have to run `make` a few times so that the configure script runs and sets things up properly. It should find libss7, and compile chan_zap with support for it. The link is brought up automatically when Asterisk starts.
Configuration in zaptel.conf is similar to that of a PRI. Your signalling channel will be set as a "dchan" and the bearer channels are set as "bchan". For information about setting up zapata.conf, see the sample zapata.conf in the configs/zapata.conf.sample in the asterisk-ss7 branch. There also is a libss7 project section on Mantis now for any bugs that you might encounter.
Oh, and BTW, I'm usually on IRC as Cresl1n if anyone has any questions as well.
