I worked for a company who used Verint for call recording. I can tell you it works but depending on how large of an installation you have it can be really difficult to get configured properly. I assume you have the toplayer devices, or whatever the new product name they have these days) mirroring the SIP and RTP traffic to and from the CIC Server and all of the media servers? You will want to make sure all of your SIP lines are set for audio to be always in so that all audio flows through the media server. I do wonder if maybe Verint can't see remote stations since I think one of the requirements of Verint is that they have to know which SIP endpoints to monitor, what a remote workstation its essentially a trunk to trunk call with no station info in it.
