I have a trunk page port set up on a 3300 CX 5.0 to interface with a Valcom Multipath. I works fine for a while but then page port busys out and I either have to restore by maintenance command or reset the 3300. The multipath port never busys out just the trunk port on the 3300. What could I look for in the settings? It has confused me since it works for a while and then it quits. Any help is appreciated.
