Is global LBR on? Is source site known and LBR enabled? Use next usage in user’s Voice Policy to check if call is authorized Normal processing Use usages in user’s Voice Policy Is call authorized by user Voice Policy? Use usages from source site Voice Routing Policy to route call Normal processing Are additional usages on the policy? Do no allow call Stop Route only to non-LBR-enabled trunks Outbound routing One policy for authorization and a different policy for routing Scenario: caller as@contoso.com is based in Atlanta and has Atlanta Voice Policy but is visiting Boston site which is LBR enabled Inbound routing Start Is global LBR switch on? Inbound from trunk? Is source trunk LBR? Get site associated with the trunk Is endpoint in the gateway site? Route to endpoint Stop Route to UM Conferencing LBR conferencing application ensures that a single conference does not contain VoIP users from different sites and PSTN dial-out Mediation Server C Gateway F PSTN gateway FQDN F Mediation Server D Gateway G PSTN gateway FQDN G Media path optimization PSTN MPLS Trunks and IP-PBX interworking Trunk and IP-PBX interworking—real life MTP-1 PBX-10 MED-10 5060 5061 MTP-2 M:N routing Session management A possible alternative for PBX integration scenarios Lync Server can support call routing from an incoming trunk to an outgoing trunk to provide routing functionalities to other systems By enabling intertrunk routing, the following routing paths (among others) are enabled: Sample scenarios Inbound trunk PSTN usage Route Outbound trunk Inbound trunk • • • • • PSNT usage Route Outbound trunk Session management Lync supports the association of a set of PSTN usages on an incoming trunk to determine a call route to an outgoing trunk Intertrunk configuration remains familiar for the administrator with the use of existing routing configuration concepts Media bypass in intertrunk routing calls is supported Intertrunk routing call authorization scope is at the trunk level Configuring session management New-CsVoiceRoute -Identity RedmondRoute -PstnUsages @{add=“Redmond"} -PstnGatewayList @{add="PstnGateway:redmondgw1.contoso.com"} Set-CsTrunkConfiguration –Identity “TrunkId” -PstnUsages @{add=”Redmond”} Lync call-handling services Call queuing, treatment, and routing for departments Unassigned numbers service Prompt playback and transfer capability for unassigned numbers Team call User define who their calls are forked to Group Call Pickup Call Park and Group Call Pickup Both features are built on the same service Call Park Group Call Pickup Call Park and Group Call Pickup—planning Orbits Clients Administration © 2014 Microsoft Corporation.
