Location-Based Routing (LBR) is a feature of Enterprise Voice that routes calls based on user location instead of Least Cost Routing (LCR). The advantage of LCR is related to costs because Lync will use the gateway that is closest to the called party (using the corporate wide area network, WAN, to reach to the previously mentioned gateway). This kind of solution minimizes tool charges. However, some reasons (the desire to minimize WAN utilization or local regulations) could require LBR to route the call to the gateway that is physically nearer to the Lync user. Lync 2013 CU1 is at least required to enable LBR. Lync Enterprise Voice configuration is a prerequirement for LBR. It is also required to configure at least a network region (a backbone or a hub in our network), a site (a geographical location, such as a branch office), and a subnet (based on the IP subnet). LBR is based on voice routing policies associated with network...
