Hi All, I have 2 MAX 3000's that I have recently upgraded to TAOS 9.04. I have then enabled stacking on these units. The 3000's are using three ISDN30's which have been configured for Cyclical dialling. The remote users are analogue diallers, pipeline isdn routers, and Cisco 803's. Ever since I enable stacking, the MAX is dropping the ISDN calls every 15 minutes or so. I am using extended PINGS to keep the calls up. BTW, when one MAX was running on it's own, it was working perfectly fine. What are the first steps that I can do to resolve this? I have already checked the remote units and they look fine. I had also temporarily disabled the stack and the calls came through normally and stayed up. Anybody out there have a clue?
