We use a pair of S8700 servers with Communication Manager 2.0 and EAS to handle calls in our call center. We have a building a mile away with an s8300 and CM 1.3 with basic call center v11. We are setting it up as a temporary/short term DR site to receive calls. We have been able to drop the calls into a pool of agents with a simple vector, however if all phones are busy we'd like to play a message asking customers to be patient and then re queue the call. Avaya is telling us we'll need to upgrade the switch and call center in order to be able to do it. Has anyone tried to do something similar with these versions?
