SIP Trunk Operations (DTSIP)

SIP Trunk Operations (DTSIP) is a 5-day instructor-led course that is intended for Cisco collaboration administrators who need to understand the features and functionality of the SIP protocol, as implemented in Cisco’s Collaboration deployments. The course begins with an examination of SIP Request and Response messages, their purpose, their meanings. We examine the Session Description Protocol (SDP) offers and answers. We explain SIP early offer and SIP early media. We also cover the purpose and configuration of Media Termination Points (MTP) and transcoders in our SIP deployments. We examine the headers that makeup all SIP messages.

Course Objectives:

After this course, students will be able to:

  • Examine and understand the purpose of SIP requests, responses, and SDP
  • Configure SIP trunks and SIP Profiles on Cisco Unified Communication Manager (CUCM)
  • Configure SIP call routing on Cisco SIP Proxy (CUSP)
  • Configure URI Call routing on both CUCM and Session Border Controllers (CUBEs)
  • Configure SIP CUBEs using a variety of features, including translation-profiles, patterns-maps, server groups, provision policies
  • Gather SIP traces from servers, CUBEs, routers, phones, endpoints
