Summary

Glare, also known as dual seizure, is a condition in which two entities attempt to select the same circuit within the trunk group; in the context of this Recommendation, the two entities are a H.323 Gatekeeper and a PSTN switch. This Recommendation specifies a mechanism that allows an egress H.323-PSTN Gateway to resolve a glare condition that is detected on the Gateway when circuit selection is done on the Gatekeeper. The Gatekeeper delivers a Glare Control Indicator to the Gateway to inform the Gateway on how to deal with the glare condition.
