BETA DOCUMENT - PRELIMINARY & CONFIDENTIAL
About IP telephony and Strata CS ________________________
Strata CS seamlessly supports Internet telephony through an integrated Internet
gateway that eliminates the need for external IP Gateway devices. Combined with
dialing services, Strata CS’s Internet telephony support makes it as easy to place
and receive Internet calls as regular telephone calls—whether you are calling
from a station phone, remote phone, or using the Strata CS Client.
Strata CS’s integrated Internet gateway supports the following Internet telephony
features:
n Placing and receiving calls from H.323 terminals, for example, Net
Meeting (see page 13-2) or Phone Dialer (see page 13-6).
n Enhancing a Web page with a Call Us! button (see page 13-6).
n Connecting Strata CS Servers over the Internet or private IP networks
(which can guarantee quality of service). See page 13-7.
Over a properly configured IP Gateway, users can:
n Call extensions on a remote Strata CS Server.
n Place calls to phone numbers from a remote Server.
n Place calls on a remote Centrex/PBX service through a remote Strata
CS Server.
Internet telephony requirements
Before using any of Strata CS’s Internet telephony features, you must first:
n Install the hardware and software required to support Internet telephony.
See Strata CS Installation & Maintenance Manual for more information.
n In the Strata CS Administrator, add and configure one or more Internet
spans (see “Adding an Internet span” on page 5-21).
n Ensure 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.

like Microsoft NetMeeting, a real-time conferencing and collaboration tool. The
diagram on page 13-4 shows how this process works.
Note:
Users who calls NetMeeting terminals might hear an echo on the line. To
