I have a customer with a DSX (was v3.09, now 3.2). In the middle of a call the caller would suddenly be cut off and put into voicemail. The customer has a PRI. This has happened on two different extensions when the caller was using the DID for the person they were talking to. In all cases it was coming from the same cell number and speaking to the caller, he did have some problems with signal.

I am inclined to think it is the cell, but that doesn't explain the call going into VM like it does. Has anyone seen anything like this?
