| | Configuring Voice over IP |
 | | Voice over IP can be used with Microsoft NetMeeting (Version 2.x) when the Cisco 3600 or Cisco 2600 series router is used as the voice gateway. | | | 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). | | | Identify the IP address of the appropriate port on the destination end router. |

| | Voice Over IP |
| | An IP address is a series of numbers that uniquely identifies a computer or device attached to the Internet. | | | While it is possible to use a computer’s microphone and speakers and special software for telephony over the Internet, the obvious limitation that the computer has to be turned on to make or receive phone calls makes this unwieldly. | | | The key to making VOIP work is the correct initialization of the TA to work with the internet phone company and configuring IP addresses on the router to use for the computer or premise LAN connected computers sharing the broadband connection. |

| | You will recall that voice is analog in its native form and that the PSTN also was entirely analog for the first 75 years or so. | | | On the receiving end, the digital signal has to be decoded (i.e., reconverted) back into an analog format in order to be intelligible to the human ear. | | | You'll recall that the TCP/IP protocol suite was conceived and developed as a means of gluing together disparate data networks, independent of host computers, hardware and operating systems, transmission media, and data link technologies. |
