Paging and conferencing on an IP-enabled 3Com. That brings back memories of many unpleasant hours spent trying to get this to work. We still have a multi branch site with PTP T1's and we had to enable IP multicast routing, make sure IP multicast dense mode was configured and then add EVERY IP multicast group listed in the programming. We finally got that working consistently.

One of the original 3COM engineers will help you for a fee. He has helped me out of some jams.

He can actually recreate a hard drive for you as a cold spare which can give you peace of mind.

Of course, I can't find his contact info but if you are interested let me know and I will find it to PM you. Multicasting is your devil in that system though. ~ Mike
