We have recently installed a complete suite of Nortel products in our call centre and we are finally getting around to installing Agent Desktop Display. After getting multicast working on our network, we have noticed that the Symposium Web Client displays are now using Multicast where before they were using Unicast to display the data. The supervisors are now complaining that their Web Client real time displays are refreshing much slower than normal. Since ADD requires multicast to work, is there a setting somewhere that needs to be modified to either speed up the refresh of the Symposium Web Client displays, or prevent them from using Multicast?
