On the other hand, you might prefer H.323 over MGCP because of the wider selection of interfaces supported.. The integrated services routing architecture of the 3800 Series is based on the 3700 Series. The Cisco 827-4V ADSL Router is a member of the Cisco 800 Series Routers. Each IP Telephony deployment model differs in the type of traffic that is carried over the WAN, the location of the call-processing agent, and the size of the deployment.

H.323 also can be used as a signaling protocol between CCM and a voice gateway. If the voice gate- way were not a Cisco product, H.323 would be the choice. One drawback of H.323 is that it does not support call survivability.. If two or more voice gateways or CallManager Express routers need to send signaling to each other over an IP network, the router configuration commands called dial peers are configured, also based on H.323.

When designing networks that transport voice over packet, frame, or cell infrastructures, it is important to understand and account for the network delay components. The PCM samples are then passed to the compression algorithm that compresses the voice into a packet format for transmission across the WAN. On the far side of the cloud the exact same functions are. Depending on how the network is configured, the router/gateway can perform the CODEC and compression functions or only one of them.

In the late 1990’s and now, in the begin- ning of the 21 st century, Cisco has taken their TCP/IP equipment to the next level—the transmission of time-sensitive voice over TCP/IP.. Let’s review some of the hardware that can be used to construct an AVVID infrastructure.. To begin the first part of the conversion phase (see Figure 1.3), the first step is to take advantage of Voice- and Video-Over IP.
