Easy to debug and to dump. SS7 over ip is being *used* by many high shelf level vendors internally in ss7 switches, no point in translating into a SS7 over TDM, and on the other end of the wire, TDM to IP. And by the way: i don't force anyone to use it, I just see some advantages. Ok, it's asterisk list, so EOT as for me, if you whould like to exchange some more arguments please go off-list, ok? -------------- next part -------------- An HTML attachment was scrubbed...
