If you plan to use
multichannel routing, you must configure one or more Media Routing Domains
(MRDs) for them. The system uses MRDs to organize how requests from different
media are routed to agents. After you add them in Configuration Manager, these
MRDs populate the Select Media Routing Domain popup window in the Dialed Number
tool. If MRDs are already configured, you might need to access this tool to
change settings such as Max time in queue or Service Level Threshold.
