Internet telephony requirements

Before using any of Strata CS’s Internet telephony features, you must first:

nInstall the hardware and software required to support Internet telephony. See Strata CS Installation & Maintenance Manual for more information.

nIn the Strata CS Administrator, add and configure one or more Internet spans (see “Adding an Internet span” on page 5-21).

nEnsure that the IP address of the Internet span on each Server is completely accessible by the other Server. To do this, you may have to configure firewalls at each location appropriately.

This chapter explains in detail how to configure and use Strata CS to make various types of Internet telephony connections.
