The following scenario shares a telephony server between sites. In this example, the
telephony server uses the PBX at site A. The telephony server is shared with site B, which
may or may not have its own PBX. Because a single telephony server instead of an array of
telephony servers is installed at site A, high availability features are not supported.

The following scenario is a variation of the previous one. An array of
telephony servers has been added, which provides redundancy, scalability, and
load balancing.
