Aggregation (CBO)#
This call type occurs when an endpoint located in a Site in one country wants to reach a destination in any country through Aggregation (Central Breakout). The cluster in which the site is located must have the source country dial plan. Routing is based on the source country. It is not possible for sites in a cluster to be in different countries.
The call type includes:
SIP/SCCP signaling traffic for the endpoint between the endpoint and Cisco Unified Communications Manager
SIP signaling traffic for SIP trunking between the SIP trunking Session Border Controller (SBC) and Cisco Unified Communications Manager
Media traffic between the endpoint and SIP trunk SBC
