The other thing that baffles me about this setup is that it only seems to happen to people who are connected to the internal network in the office. They have about 30 remote users that have not reported this same problem, their issue is usually bandwidth related from their home connection.
We have checked the internal network several times and there is not any obvious problem (apart from the dropped calls). They use high end Cisco switches and they were just audited to make sure there were no configuration errors. All the internal phones are Aastra (most are 9133i and some others 53i).
