In the Inter Network Region Connection Management screen, the second page with the region-to-region connection administration does not display.
Although fully H.323v2-compliant products of other vendors have shuffling capability, you must test the endpoints before administering such endpoints for shuffling. See Determining whether an endpoint supports shuffling.
SIP Early Direct Media
Communication Manager supports SIP Early Direct Media for Session Initiation Protocol (SIP) calls. Direct Media signals the direct talk path between SIP endpoints before a call connects.
Direct Media provides the following enhancements to SIP calls:
Eliminates shuffling of SIP calls after the call connects.
Eliminates clipping on the talk path.
Reduces the number of signaling messages for each SIP call.
Reduces Communication Manager processing for each SIP call and increases the capacities of Communication Manager and SIP Busy Hour Call Completions (BHCC).
Determines the media path early in the call flow and uses fewer media processor resources to configure the system.
