I'm connecting 3 each 2k systems via msdn, clustered, everything is fine. We've placed a pair of 3300LXs between two of the 2ks, msdn into the 3300s and IP (xnet) between the 3300s. When I busy the main route (P2P msdn) to force traffic over the 3300s, the calling party sees "invalid digits" on the display and hears a fast busy. I'm sure it's something right in front of me - any suggestions? Thanks in advance!
