Dear Matthew, I found other bugs on the code when connecting 4 different point codes but one adjacent signaling link (fixed). Also, I could not connect 2 signaling channels to the same linkset. There is a sync issue FIB/BIB when we have more than one sigchannel. Can I contact you off-list? Can I send to you patches (chan_zap & libss7)?
