Yes- you will definitely see abandons double peg from a skillset view in a networked environment. From an application view abondoned calls only peg once. It actually makes sense which is hard to believe since we are talking about Nortel reporting. Example- call is waiting at CS appl at Site A. Through Site A CS appl- CS skill is queued to at sites A, B, and C. After 30 seconds (before an agent in CS skill becomes idle) the customer decides to hang up. Call pegs as abandoned in Site's A CS appl. At skillset view- call pegs as abandoned in CS skill at Site's A, B, and C. So if you would run a skill report from Site A, B, or C you would see this call abandoned.
In our environment we have 6 networked CCMSs. For certain skills we see the call abandon at each site or 6 times. We've had to modify what report tables (appl vs skill) for certain information. Use appl for calls abadoned if possible. If you use skill, divide abandons by number of sites skill is networked to.
