I'm the one who posted the original question, and yes, I *am* experiencing dropped calls. I haven't yet been able to correlate the dropped calls with anything, and that is why I asked the question about the PRI warnings and notices. Also, our volume of calls is very light...maybe 3-4 calls/hour. But, the dropped calls are very frequent and predictable...predictable in the sense that if you plan to talk for more than 5 minutes, there is a high likelyhood your call will be dropped.
We are running on a relatively small system...700mz celeron, 128mb, slow disks, and a bios that tends to like to put as much as possible on the same IRQ. So, I am hoping the messages, and the solution to our problem with dropped calls has to do with a shortage of resources. We plan to upgrade the system to a 3gz P4 in the next few days, and I will post the results of that upgrade when I determine if the problem goes away.
