Microsoft® Lync Server 2010 Unleashed

On-Net and Off-Net Voice Routing

For an enterprise to benefit from a large geographically dispersed voice network with many PSTN egress points, the capability to route calls through these points is crucial. However, when the points are located in different cities or countries, each point can require different dialing formats, prefixes, or other access codes. This can add tremendous complexity to a corporate dialing plan. Fortunately, Lync Server provides central alternative routes and number-formatting changes to manipulate the dialed number prior to routing to a PBX or the PSTN.
