Feature Overview
Voice over IP (VoIP) enables a Cisco AS5800 universal access server to provide voice and fax traffic,
such as telephone calls and faxes, over an IP network. There are basically two different environments
in which VoIP can be deployed: enterprise and service provider. Different strategies have been
developed for deploying VoIP in both of these environments. The Cisco AS5800 universal access
server can be configured for deployment in either an enterprise or a service provider environment
but, because of the extensive capabilities of the Cisco AS5800 universal access server, it is more
likely that it will function as a carrier class gateway in a service provider environment. This
document, then, describes how to configure the Cisco AS5800 universal access server to act as a
carrier class gateway in your VoIP network. To configure the Cisco AS5800 universal access server
to perform in an enterprise environment, refer to the Cisco IOS Release 12.0(3)T Voice over IP for
the Cisco AS5300 feature module. The configuration steps for both the Cisco AS5300 access server
and the Cisco AS5800 universal access server for an enterprise environment are identical.

Voice over IP in either the service provider or enterprise environment is primarily a software feature;
however, to use this feature on the Cisco AS5800, you must install a VoIP feature card (VFC). The
VFC uses the Cisco AS5800’s T1/E1 and T3 Public Switched Telephone Network (PSTN) interfaces
and local-area network (LAN) or wide-area network (WAN) routing capabilities to provide up to a
192 ports or channels (per VFC card) for VoIP packetized voice traffic.
