Agents logged into the hot desk hunt group do not appear as logged in and available. Calls to their phantom device are forwarded to voicemail. Additional attempts to log into the same hunt groups display a message on the phone that they are already logged into that hunt group. The problem is fixed by restarting the Xarios application service and having the agent log out and then in. Restarting this service during call center operations is not a good option. Has anyone else had this problem and know of a fix?
