I have used Rex Remedy and Vantive in the past. Vantive is more feature rich that Remedy. We had Tech Support on side and Sales on the other. It was pretty cool stuff. They modified it to accept mail support too. Remedy was modified to use a CTI which was pretty cool too.
In my current position, before we outsourced, one of the guys I work with built an Access Db to do our calls.
