Deployment process for Location-Based Routing in Lync Server 2013

  • Artikkeli

 

Topic Last Modified: 2013-03-09

This topic provides an overview of the process involved in configuring Location-Based Routing. You must deploy Lync Server Enterprise Edition or Standard Edition with Enterprise Voice before you configure Location-Based Routing. The components required by Location-Based Routing are already installed and enabled when you deploy Enterprise Voice.

Sample Deployment

The following deployment is used to illustrate further the mechanisms enabled by Location-Based Routing.

Incoming PSTN calls

An administrator can enable the trunk defined to route calls to “Site 1 Gateway” for Location-Based Routing and associate the “Site 1 Gateway” to site 1. Once enabled, calls that are routed through “Site 1 Gateway“ will only be routed to users that are located in site 1. All calls routed through the “Site 1 Gateway” trunk destined to users in a different site, such as site 2 will be blocked to prevent PSTN toll bypass.

All incoming PSTN calls through “Site 1 Gateway” will only be allowed to route to endpoints located in site 1. For example, when “Lync user 1” travels to site 2, all incoming PSTN calls through “Site 1 Gateway” will not be routed to “Lync user 1” endpoints located in site 2. The same routing rule applies if “Lync user 1” travels to an unknown network site where the user’s location can’t be determined.

The following table outlines the user experience of “Lync user 1” in this context.

Lync user 1 endpoints located in network site 1 Lync user 1 endpoints located in network site 2 Lync user 1 endpoints located in unknown network site

Calls are routed to endpoints in this location

Outgoing PSTN calls

Voice routes are referenced in both Voice Policies assigned directly to users, and Voice Routing Policies assigned to network sites. Both policies contain references to routes, which can be used to route a call differently. For example, an administrator can define a Voice Routing Policy for all users located in network site 1 to route all outbound calls through the “Site 1 Gateway” while the Voice Policy of some users define a route for all outbound calls through the “Site 2 Gateway”. While these users are located in network site 1, their outbound calls will be routed through the “Site 1 Gateway”.

When a user is located in a network site configured for Location-Based Routing, the network site’s Voice Routing Policy route overrides the user’s Voice Policy route. This rule is particularly useful for users that temporarily move to a different site. In this particular case a user will always use a gateway that is local to his location; if “Lync user 3” is located at “Site 2”, all his outbound calls will be routed via “Site 2 Gateway”, but if he travels to site 1, all his outbound calls placed while he’s at site 1 will be routed through “Site 1 Gateway”.

The following table illustrates the user experience of Lync user 1 placing an outbound call from the following network sites.

Network site 1 Network site 2 Unknown network site or not enabled for Location-Based Routing

Authorization of outbound calls

Lync user 1 voice policy

Lync user 1 voice policy

Lync user 1 voice policy

Routing of outbound calls

Site 1 voice routing policy

Site 2 voice routing policy

User’s voice policy and only to systems not enabled for Location-Based Routing

Call transfers and forwards

When calls are transferred or forwarded, the routing of calls is affected by Location-Based Routing.

The following table depicts Lync user 1 transferring or forwarding a PSTN call to another Lync user.

User initiating call transfer or forward Lync user 2 Lync user 4 Lync user in network site not enabled for Location-Based Routing

Lync user 1

Call forward or transfer is allowed

Call forward or transfer is not allowed

Call forward or transfer is not allowed

The following table illustrates how Location-Based Routing affects how the call is routed based on the location of the Lync user being transferred (Lync user 2, Lync user 4, etc) to a PSTN endpoint

Endpoint where call is transferred or forwarded to Lync user 2 Lync user 4 Lync user in network site not enabled for Location-Based Routing

PSTN endpoint

Call forward or transfer is routed through site 1 voice routing policy and egress via Site 1 Gateway

Call forward or transfer is routed through site 2 voice routing policy and egress via Site 2 Gateway

Call forward or transfer is routed through the Lync user voice policy and egress via a gateway not enabled for location-based routing (if available)

Simultaneous ringing

Once location-based routing is configured in the sample topology, the following interactions are enforced.

The following table illustrates whether Location-Based Routing allows simultaneous ringing for different Lync users (i.e. Lync user 2, Lync user 4, etc).

Incoming PSTN call target Lync user 2 Lync user 4 Lync user in network site not enabled for Location-Based Routing

Lync user 1

Simultaneous ring is allowed

Simultaneous ring is not allowed

Simultaneous ring is not allowed

The following table illustrates whether Location-Based Routing allows simultaneous ringing to a PSTN endpoint from different Lync users (i.e. Lync user 2, Lync user 4, etc).

Simultaneous ring target Lync user 2 Lync user 4 Lync user in network site not enabled for Location-Based Routing

Lync user 1 mobile phone (PSTN endpoint)

Call routed through network site 1’s voice routing policy and egress via site 1 gateway

Call routed through network site 2’s voice routing policy and egress via site 2 gateway

Call routed through the caller voice policy and will egress via a PSTN gateway not enabled for Location-Based Routing
