there are three sites with centralized design model. only one site has callmanager and the other two sites only gateways which phones in remote sites register through callmanager. I have a question as far as device pool. I need two remote site use SRST in the case of callmanager failure. so I have to create three device pool for all three sites and assign SRST reference to each device pool. But the problem is: media termination point, MOH, Transcoder are in default device pool. How can I make all of these available to all three sites whereas I have four device pools?
In the device pool you can select the MRGL. So you will have to create three different MRGL, one for each site, and assign them to the respective device pool.
