Use the following procedure to activate the service. Procedure Step 1 Access Cisco Unified Communications Manager Serviceability. Step 2 Choose Tools > Service Activation.
Shall I activate TAPS service on publisher or in suscriber?. I have already running TAPS service in publisher but no in suscriber.
Configuring Auto-Registration Options for TAPS
Step 1 In the Cisco Unified Communications Manager Administration window, choose System > Service Parameters. The Service Parameter Configuration window displays. Step 2 From the Server drop-down list, choose the appropriate server.
What server?, publisher or suscriber?
