Would it not work for you to just setup a single linkset in zapata.conf using two signalling channels within the linkset? It would seem that since you're receiving ISUP traffic for CICs on the other port, that they are both part of the same linkset anyways and that would be the implied setup. -- Matthew Fredrickson Software/Firmware Engineer Digium, Inc.
