Random delays when retrieving messages from the phone

So ever since we changed our integration from 55 off box to 2K off box, we've been having this problem.

If you dial into the VM system, it quickly answers and asks for your password. Most of the time, it works fine. But about 10% of the time, it hangs after accepting your password for anywhere between 15 to 1 minute and then says "you have X messages". But it's not just there... sometimes after it tells you that you have X messages, and you press 1 to listen to new VMs, it will pause for 30 seconds then say "new messages, message 1...".

I've also noticed that if my officemate dials in and gets delayed, and then I quickly dial in, I'm hung up as well... then we both release at the same time with whatever greeting prompt we're waiting for... so it's not user specific, the Unity system as a whole is hung up.

The NIC and switches are both set to 100FULL (not auto) and all other functions seem to be working fine.

Any thoughts?

When this happens can you open the task manager on the Unity server to see if any processes are pegging the cpu, you might even open the Unity status monitor to see how many calls and who is logged in.

You might have a look at the following links.

Re: Random delays when retrieving messages from the phone

I would look at the Exchange mail box sizes and number of messages. There is a direct correlation between mailbox size and delay.
