Configuring Voice over IP
This chapter explains how to configure voice interfaces and ports, which convert telephone voice signals
for transmission over an IP network.
This chapter presents the following major topics:
• Prerequisites, page 4-1
• Configuring the Voice Interface, page 4-2
• VoIP Configuration Examples, page 4-4
VoIP enables your Cisco IAD to carry live voice traffic (for example, telephone calls and faxes) over an
IP network. VoIP offers the following benefits:
• Toll bypass
• Remote PBX presence over WANs
• Unified voice and data trunking
• Plain old telephone service (POTS)–Internet telephony gateways
For more information on understanding and configuring VoIP, see the Configuring Voice over IP
document.
Prerequisites
Before you can configure your Cisco integrated access device (IAD) to use VoIP, you must first do the
following:
• Establish a working IP network.
