SIP Trunk Optimization
This course explains exactly what SIP is, what options are available, and how it is used to facilitate communication between various endpoints, such as Cisco Session Border Element (CUBE), Cisco SIP Proxy server, and the PSTN. Students will learn how to use troubleshooting tools to identify and solve a variety of problems that arise during deployment as well as during day to day operations. The course will also use URI "click to call" device independent user addresssing the SIP Intercluster Lookup Service (ILS) and Global Dial Plan Replication (GDPR) features to dynamically distribute the dial plan throughout the enterprise.
