Cisco IP Communications Voice/Fax Network Module
Cisco IP Communications Voice/Fax Network Modules for the Cisco 2800, 2900, 3800, and 3900 Series
Unified Communications Routers
The Cisco
®
IP Communications voice/fax network modules provide enterprises, managed service providers, and
service providers the ability to directly connect the public switched telephone network (PSTN) and traditional
telephony equipment (private branch exchange [PBX], key system, analog telephones, fax machines, etc.) to Cisco
2800, 2900, 3800 and 3900 Series Unified Communications routers. This set of Cisco IP Communications voice/fax
network modules delivers the most versatile combination of analog and digital voice and data capabilities in a single
network module. As a completely integrated component of the Cisco Unified Communications solution including
Cisco Unified Communications Manager (UCM), Cisco IP phones, Cisco Unity
®
unified messaging software, Cisco IP
Contact Center (IPCC), and the entire line of Cisco IP Communications products, the Cisco IP Communications
voice/fax network modules are a cornerstone of Cisco Unified Communications. When used in a Cisco unified
communications router with Cisco UCM, Cisco Unified Survivable Remote Site Telephony (SRST), or Cisco UCM
Express, the Cisco IP Communications voice/fax network module is a complete IP Communications solution for the
business branch.
Figure 1 shows the IP Communications voice/fax network module with one VWIC2-2MFT-T1/E1 and one VIC3-
4FXS/DID.

The Cisco IP Communications voice/fax network modules for the Cisco 2800, 2900, 3800, and 3900 Series unified
communications routers enable packet voice technologies including VoIP (H.323, Media Gateway Control Protocol
[MGCP], and Session Initiation Protocol [SIP]). Cisco Unified Communications solutions provide the means for
integrating voice and data within a single network, allowing users to take advantage of services such as IP
telephony, integrated services, and toll-bypass while providing an opportunity to improve productivity. By operating
on Cisco IOS Software, these solutions incorporate advanced quality-of-service (QoS) features, intelligent network
queuing, and standards-based encapsulation, providing efficient direct transport of both voice and fax over IP
networks. Cisco IOS Software solutions enable time-sensitive voice traffic to be moved across even low-bandwidth
WAN connections with the priority and quality that voice and fax demand. Transporting voice over IP networks
continues to provide transport flexibility because IP can be routed across a multitude of WAN technologies (leased
lines, Frame Relay, and ATM) along with providing direct connectivity to the desktop.
