I know this is a stretch, but I used to have this issue with XTS systems that received their PRI service from soft switches. There was an issue with the format of the caller ID information (I believe they were sending too many characters) and it was causing this exact same issue. We were able to prove this by asking the service provider to temporarily stop sending call data and the problem went away. I know it doesn't answer your question, but it might help.
