Yeah, that's probably going to be something we'll have to deal with. A lot of switches I have seen don't cross T1/E1 boundaries on group messages, but Asterisk's SS7 implementation has situations where it does cross T1/E1 boundaries on group messages. For A links, I think it won't be a problem though because the CICs are going to line up correctly. For F links (signaling and bearers on same T1/E1) you'll have problems with lining up group messages with T1/E1 boundaries. > When I have time I'll test your new stuff. It's actually in the svn branches I posted earlier which contain Domjan's changes... I'm going to have to merge those into trunk anyways, I just haven't done it yet, so eventually they'll be in trunk. http://svn.digium.com/svn/libss7/branches/mattf/bug13495 http://svn.digium.com/svn/asterisk/branches/mattf/bug13495 Matthew Fredrickson Digium, Inc. > > Regards, > Attila > >> Well, to have a fully redundant setup, you would have separate boxes >> terminating each signaling link.
