I already passed an interconnect test with another stuff. It was very hard, have to pass a large set of tests. I just looked in the libss7/chan_dahdi. I may able to implement some isup related features (call forward count, other types of nature of address etc...) but the mtp level seems difficult for me. If we choose libss7 for interconnect I won't have too much time fixing the issues during the test.
