We have a client with a 3300 CXi II. Their hard disk was failing so we had to replace it. We took a backup, but had to put MCD 4.2 PR1 on the new drive, backed up version was 4.1. The restored data appeared to go back on fine, but I noticed that users could not dial out. I had to re-program the COS for Trunks and Sets, so I wonder what else didn't go back on.
The only other problem we have is that audio both dialling out or calling in is very poor, like your talking to someone with a poor mobile signal. It's very choppy and crackly. I've called out from various sets, answered calls on various sets and used individual trunk access to dial out on different trunks. They are using a Quad BRI linked to 3 x BT ISDN 2 devices. Calls internally are fine, so I assume it's something to do with the Trunk. Also worth a mention that the inbound answer point is an Auto Attendant, which sounds awful too. But if you dial it from inside the network it's fine.
Some phones are powered by a Cisco POE switch others are using the CXi's switch, problem occurs on both.
