SIP TRUNK OPERATIONS (SIPTO)
Course Overview
SIP Trunk Operations (SIPTO) is a 5-day instructor led course that is intended for Cisco telephony administrators who need to understand the features and functionality of the SIP protocol, as implemented in the Cisco Unified Communications environment. The course begins with an examination of how SIP is used to establish, manage, and terminate sessions over an IP network. Next, it discusses the various types of SIP trunk options available within Cisco Unified Communications Manager. SIP proxy and line-side configurations for user devices (phone, mobile, tablet, video) are covered and the course also includes SIP troubleshooting techniques and practice through hands-on labs. This course describes what SIP is, what options are available, and how it is used to facilitate communication between various components, including Cisco Unified Communication Server, Cisco Unified Border Elements (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 and in day-to-day operations. The course will use URI ’click to call’, device independent, user addressing, the SIP Intercluster Lookup Service (ILS) and Global Dial Plan Replication (GDPR) features to dynamically distribute the dial plan throughout the enterprise. Sunset Learning developed this course to provide additional training for those who already have a basic understanding of Cisco Unified Communications Manager and are looking to use SIP in their infrastructure. This is not a certification or implementation course.
