IPMA managers only have the ability to change the divert target from the IPMA Manager Configuration page. This allows them to direct incoming calls to another attendant.
It's so obvious, the question is almost difficult. Configuring Cisco IPMA in shared-line mode requires lines to be shared DNs between the manager and assistant.
Shared-line mode is supported by the CallManager 4.x versions and enabled features not previously supported in the proxy-mode, such as Call Join, Privacy, and Direct Transfer.
B and C
The three flagship Cisco IP Phones support IPMA: The Cisco 7940, 7960, and 7970.
Shared-line mode supports a maximum of 10 assistants per manager.
Cisco used the Tomcat server (developed under Apache) applied as a Windows service to manage many of the additional services that previously required the Customer Response Solution (CRS) software add-on.
After changing the service parameters, the MA Servlet must be restarted through the Tomcat web server.
From this list, the first thing you must configure is the IPMA manager. You can then add assistants and install the Assistant Console.
The IPMA Assistant Console is installed from a custom IPMA page managed by the Tomcat web server. By accessing the URL http:///ma/Install/IPMAConsoleInstall.jsp, an automated script runs and places shortcuts on the assistant's desktop and Start menu to run the application.
The IPMA service communicates to all servers in a CallManager cluster by using the CTIManager. It only requires a single CTI connection for all users in a cluster.
