Overview

SIP Trunk Operations (SIPTO) 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 SIP Request and
Response messages, their purpose, their meanings. We examine 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. Next, we examine the features and capabilities of CUCM SIP
trunks. We cover the purpose of options available on the CUCM SIP Profiles that are used for trunks, and
line-side endpoint configurations. We will configure SIP URI dialing on CUCM. We will use ILS, GDPR,
and an SME server to dynamically distribute the dial plan among multiple CUCM clusters. We configure
the Cisco SIP Proxy to route enterprise calls. We will configure Session Border Controllers (CUBES) for a
variety of connective purposes. We will demonstrate how the use of E.164 Pattern Maps and ServerGroups will significantly improve and simplify the CUBE configuration. We examine the call routing logic
of both inbound and outbound dial peers. We configure Voice Translation Profiles and Dial Peer Groups.
We configure URI Call Routing on the CUBE and demonstrate how Provisioning Policies allow
administrators to select outbound dial peers based on inbound dial peer matching. We show you how to
configure SIP Normalization on both the CUBE and CUCM, as well as how to configure the SIP
OPTIONS ping keepalive feature. In this course, we will spend an extensive amount of time
Troubleshooting SIP calls. We will demonstrate many ways to collect SIP Traces and Debugs and show
you how to use diagnostic programs that are available to examine and understand the various SIP debug
and trace output. Finally, you will configure a summary lab that will challenge you to use the knowledge
and skills you will have learned throughout the course. You will configure an end-to-end SIP solution
using multiple CUCM clusters and CUBEs. You will fulfill a list of SIP configuration requirements like what
you will encounter in your real world collaboration deployment.

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
  • Diagnose and resolve SIP call routing
    issues, including one-way audio,
    misconfiguration, and many other
    commonly encountered ’real world’
    issues
  • Configure and troubleshoot SIP
    throughout their collaboration enterprise

Audience

  • Cisco Unified Communications Manager
  • Professionals with CCNA Voice and/or CCNP Voice Certification
  • Customers that need to better understand the SIP protocol

Prerequisites

To fully benefit from this course, students should have the following prerequisite skills and knowledge:
