[Users] Realtime Call Monitoring

We are Asterisk-only users and currently use Asterisk Flash Operator Panel (http://www.asternic.org/) to get a real-time view of the different phones/extensions, channels, etc. We are planning on enhancing our setup by adding SER/OpenSER in front of our Asterisk systems and to expand into other venues as well. If we wanted to use something like SEMS instead of Asterisk for certain services, is there any tool similar to the Flash Operator Panel (FOP) available for SER/OpenSER + SEMS? I guess we could always continue using FOP with our Asterisk systems fronted by SER/OpenSER. However, for our other plans where we prefer to use SEMS, we would love to see if there is any solution available (free, sponsored, or commercial). Thanks, Daniel
