we have been using 3rd party cloud based contact center with Cisco 7821 phones. I am running into weird issue with call monitoring...Supervisor selects an Agent which she wants to monitor and call proceeds. Supervisor can hear Agent and customer talking. Once Agent finishes the call with the customer, Supervisor's Cisco 7821 phone never disconnects the call...it freezes and you can't really do anything until you unplug the network cable from the phone. Can anyone suggest something for me to try? As far as call monitoring goes, there is no special configuration require. Thanks
