323 device that provides call admission control and centralized dial plan resolution. Otherwise, the network administrator at each of the sites must configure a full dial plan to reach all devices on the network. Additional gatekeeper guidelines include the following: • Cisco recommends that you use backup gatekeeper support to provide a gatekeeper solution with high availability. It is also recommended that you use multiple gatekeepers to provide spatial redundancy within the network. • Cisco recommends that you use a single WAN codec.
Maximum uptime; however, no more than a 20-ms round-trip delay can exist between servers d. high availability; however, you might overwhelm the backup servers 3. A single cluster that spans multiple sites can have which two benefits compared to a branch office in a multisite WAN with a centralized call-processing deployment? ) a. completely self-contained individual sites b. WAN bandwidth cost savings c. a common dial plan across all sites d. more IP Phone features during failover e. scalability to hundreds of sites 4.
This directory stores authentication and authorization information about users and is standard with Cisco CallManager (it does not require any special configuration or installation). Maintaining a user database for your IP telephony system is optional, as the phone system will work just fine without requiring users to log in to the system. However, if you want to deploy any of the advanced features such as Extension Mobility or the Cisco IP SoftPhone, user authentication is necessary. Authentication establishes the right of the user to access the system, whereas authorization identifies the telephony resources that a user is permitted to use, such as a specific telephone extension.
