(are you willing to > sign disclaimer for digium?) I do not own the copyright to the code, so it is not possible for me to sign it over. (The code is GPL, but I understand that to get into libss7, Asterisk would want full rights to re-license commercially). But in any case I can't see how the chan_ss7 code could be used in libss7. The designs are very different. While libss7 is a library that mostly replaces libisup and reuses the existing chan_zap, chan_ss7 is build as a low-level ss7-only channel driver. This means that chan_ss7 has to re-implement all of the non-signalling stuff (and has probably far fewer such features compared to chan_zap, and more bugs). But I designed it that way since I felt it was necessary to get full support for fault tolerance and failover, that would seem difficult to introduce in just a replacement to libisup in an existing driver without any clustering support. But then I never looked in any detail at libss7, so I could be completely wrong. > chan_ss7 is not developed anymore from your move from sifira to mysql i > think Actually that is not true. Anders and Jacob from Sifira did a great job continuing the development, for example all of the clustering support was done after my move. So I know that development has definitely continued. I don't know what their plans for future releases are though. But I'm definitely extremely pleased to see all the cool stuff that people are doing with chan_ss7! I hope it will continue and be successful, and that the community can continue development as time goes on. - Kristian.
