In 1994, W. Richard Stevens and Addison-Wesley released a networking vintage: TCP/IP Illustrated. The version for that publication was once an excellent, unfettered method of networking thoughts that has confirmed itself over the years to be well-liked by readers of starting to intermediate networking wisdom. The Illustrated community takes this popular procedure and modernizes it by way of growing not just a far greater and extra advanced community, but in addition by means of incorporating the entire networking developments that experience taken position because the mid-1990s, that are many.

Note You must install a Cisco CallManager publisher server before you can install any subscriber servers. When you are configuring a subscriber database server, ensure that the server that you are installing can connect to the publisher database server during the installation. This connection facilitates the copying of the publisher database to the local drive on the subscriber server. You must supply the name of the publisher database server and a username and password with administrator access rights on that server.
Because the IP Phones manage this RTP media path themselves, the Cisco CallManager is able to move out of the call-processing functions for this call. The IP Phones require no further communication with Cisco CallManager until either Party A or Party B invokes a feature, such as call transfer, call conferencing, or call termination. Even if the Cisco CallManager were to fail during the course of the call, the RTP stream would continue until one of the parties involved in the call decided to disconnect the call.
When the publisher is down, the subscribers store CDRs until the publisher comes back online, and then the subscribers update the publisher with the CDRs. 3 and later, a single cluster is capable of handling approximately 30,000 Cisco IP Phones. This cluster limitation does not restrict the size of the voice over IP (VoIP) network. By creating additional clusters, you can increase the network size. However, the more clusters you create in a network, the more management the network requires to operate.
