We're currently running firmware 8.3.3 but have had similar issues with firmware 8.0.1 till now.
As for same switches - no. multiple switches / multiple locations

We're running CCM 4.2.3 and the phone has no shared lines.
We'll try the 8.3.4SR1 firmware on Monday. I did not see the release notes on this version. What is issues are resolved in it?
