We are in a small situation with our Call Manager Network and I wanted to bounce a few things off everyone in this community.
We have 1 publisher, 4 subscribers, and about 1800 phones, on the way to 5000. We are a large medical facility in SC and are starting to experience some major pains with our system. We have opened a TAC case with Cisco about the issues of delays, echos, transfer problems, etc. They started off light and have gradually increased. Cisco is telling us we should reboot the servers starting with the publisher. They also told us that we should plan on rebooting them about every three to six months.
I see this as a big problem. As a medical facility, we cannot facilitate a reboot of 5 servers every 3 months. We have several services that run 24/7/365 and cannot go down.
My question really pertains to others who have large IPT networks and have situations where downtime is not really an option. How do you handle these issues?
Thanks in advance for any replies.
