Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Call Flow Example

This chapter provides information about a typical call flow in an IP telephony environment. Figure 19-1 shows a call flow that illustrates the actions in a typical call between the following devices at two different sites:

•Cisco Unified IP Phone (SCCP)

•Cisco Unified CallManager

•Gatekeeper

This call flow is representative of several test calls performed as part of Cisco Unified Communications Release 5.0 testing. For example, this call flow represents the signaling required to establish a call from the San Jose (SJC) site to the San Francisco (SFO) site (see Chapter 1, "Tested Deployments and Site Models" for a description of these sites).
