• The conference bridge is chosen from the MRGL of the conference controller, the party that initiates the conference. in context
• The default MRGL is always searched, and it is the last resort when neither the device MRGL nor the device pool MRGL has an available resource, or when no MRGL is configured. in context
• A media resource that belongs to no media resource group is automatically part of the default MRGL. in context
• When a device has an MRGL on the device and another on its device pool, Unified CM searches the device-level MRGL first and then the device pool MRGL. in context
• Unified CM uses a media resource from the next MRG in the same MRGL only after every resource in the current MRG is exhausted. in context
• All resources in one MRG are treated as equal, and Unified CM shares load among the resources of each type in that MRG. in context
• When a call leaves through a gateway and needs an MTP, the MTP is selected from the gateway's MRGL. in context
