Wondering if any one has had issues with 323 trunking, I have a CS1k at one end and BCM50 at the other, BCM has 4 323 trunks pointing to CS1k and 2 analog trunks for local incoming with approx 15 tdm sets, recently I am getting the first call across 323 trunks working fine, next call there is dead air and some times no ringing on BCM from pbx, they are running on target lines and the one main target line rings on all sets, if I drop the appearance to 10 sets or less it works fine, anything over ten sets it will not ring or dead air. Any info would be appreciated.
