I have no knowledge of current helpdesk systems or their ability to use CCS data. That would probably be a selling point advertised by the helpdesk software. Our clever Professional Services people handle this sort of thing all the time, so they would know too.
In any case, any helpdesk system *could* be integrated with CCS; it's just a question of how much programming and data-massaging will be required. Some will surely be straightforward, while others may require so much data transformation that they would not be worth the trouble.
