Unique Call Correlator ID (Tag: 5000)

Table 1-202 Unique Call Correlator ID Description Form

Name: Unique Call Correlator ID

Tag: 5000

Source:

MDL/Engine/External

Description/Purpose: A Unique Call ID can be created by an MGC or a media gateway, depending on the origin of a call. The purpose of this field is to uniquely identify a single call across a multinode Cisco MGC solution, and/or to provide a common key for all involved recording systems. This information can be used to associate external billing information, such as RADIUS records, and correlate multiple Cisco MGCs to what is considered a single call. The records created by the various network elements can be used by downstream systems (that is, mediation) after correlation for billing and other purposes.
