Avaya Unified Communications Custom Software LSP Redirect Using Special Coverage Point

In general stations on inaccessible port networks or media gateway controlled by local survivable processor (LSP) are considered busy and any calls to those stations whether internal or external are treated with busy criteria. In service provider network when the WAN link fails, all the incoming PSTN calls reach primary CM. CM treats IP phones registered to LSP as out of service and call fails with user busy release cause if no coverage path is administered or calls are covered to voicemail if coverage path is administered. This is unacceptable scenario for service providers and so this green feature is needed. This feature gives the ability of routing calls to stations controlled by local survivable processor (LSP) over public network/PSTN. The call is routed by administration of special coverage point and using remote coverage feature.
