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.

Introduction

This article relates to Cisco TelePresence Video Communication Server Expressway.

Q. Can I have a VCS as an Alternate to my Gatekeeper or Border Controller?

A. No. In H.323, units which act as gatekeepers (such as the TANDBERG VCS, TANDBERG Gatekeeper and TANDBERG Border Controller) can be configured as Alternates to each other. If one unit fails the other can take over and route calls as normal. That requires both units to have an identical configuration, or the call routing might change when endpoints start using the Alternate. As VCSs, Gatekeepers and Border Controllers are all different products, they cannot have the same configuration and can not be used as Alternates.

A VCS can only have other VCSs as its Alternates; a Border Controller can only have other Border Controllers as its Alternates; and a Gatekeeper can only have other Gatekeepers as its Alternates.
