Note For current information about supported hardware, see the release notes for the platform and
Cisco IOS release being used.
Cisco 800 Series Routers
Cisco 803 and Cisco 804 routers support data and voice applications. The data applications on these
routers are implemented through the ISDN port, and the voice applications are implemented with ISDN
Basic Rate Interface (BRI) through the telephone ports. If a Cisco 803 or 804 router is being used,
connect two devices, such as an analog touch-tone telephone, fax machine, or modem through two fixed
telephone ports, the gray PHONE 1 and PHONE 2 ports that have RJ-11 connectors. Each device is
connected to basic telephone services through the ISDN line.
For more information, refer to the Cisco 800 Series Routers Hardware Installation Guide.
Cisco 1750 Modular Router
The Cisco 1750 modular router provides Voice over IP (VoIP) functionality and can carry voice traffic
(for example, telephone calls and faxes) over an IP network. To make a voice connection, the router must
have a supported VIC installed. The Cisco 1750 router supports two slots for either WAN interface cards
(WICs) or VICs and supports one VIC-only slot. For analog connections, two-port VICs are available to
support FXO, FXS, and E&M signaling. VICs provide direct connections to telephone equipment
(analog phones, analog fax machines, key systems, or PBXs) or to a PSTN.
For more information, refer to the Cisco 1750 Voice-over-IP Quick Start Guide.
