Hi, We are running libss7 with 3 E1s. First E1 has the signalling channel on 16 and the others are connected to two different DPC (different destinations). The point is: CICs of link #2 and #3 are numbered from 1 to 31. They have the same number and function ss7_find_cic() can not find the correct PVT (channel) when looking for CIC number 1, for example, on GRS,GRA,BLO, etc.. I am working on a patch to handle OPC information (structure ss7_event / ss7_event_ciconly) and pass this information to ss7_find_cic for such commands. Any comment/suggestion is welcome. []'s Daniel
