Tài liệu Configuring Voice over IP for the Cisco 3600 Series

This chapter shows you how to configure Voice over IP (VoIP) on the Cisco 3600 series. For a deion of the commands used to configure Voice over IP, refer to the “Voice-Related Commands” chapter in the Voice, Video, and Home Applications Command Reference. VoIP enables a Cisco 3600 series router to carry voice traffic (for example, telephone calls and faxes) over an IP network. Voice over IP is primarily a software feature; however, to use this feature on a Cisco 3600 series router, you must install a voice network module (VNM). TheVNMcan hold either two or four voice interface cards (VICs), each of which is specific to a particular signaling type associated with a voice port. For more information about the physical characteristics, installing or configuring a VNM in your Cisco 3600 series router, refer to the Voice Network Module and Voice Interface Card Configuration Note that came with your VNM.
