Are there any 3rd party ACD products that work with the UC540/560? We have a potential customer with a small call center of 6-8 people. They want the ability for everyone to see who is logged in and if they are on the phone or not. They would also like to see how many calls are in the queue with timers running.
Have you looked at using the built-in B-ACD functionality of the UC540/UC560? For a small call center type of application this typically works well. You could also implement the Smart Call Connector application in order to see who is on the phone or not and you can all configure the B-ACD to pull call reports which you can see examples of in the document at the B-ACD link above.
