SIP Trunk Operations (DTSIP)
Sunset Learning Exclusive
SIP Trunk Operations (DTSIP) is a 5-day instructor-led course designed for Cisco collaboration administrators seeking in-depth knowledge of SIP protocol operations within Cisco’s collaboration deployments.
This updated course offers new tools and labs to enhance skills in advanced troubleshooting, automation, and real-world problem-solving. With a focus on the latest Cisco Unified Communications Manager version 15, participants will explore modern practices, such as SIP trace analysis, AI-powered solutions, and DevOps programmability. In addition to mastering traditional SIP technologies, participants will gain the foundational knowledge required to configure Cisco Unified Border Element (CUBE) for enterprise PSTN access and Webex Calling.
New Content and Labs
- In-depth SIP Trace Analysis: Learn to use Wireshark, RTMT, and TranslatorX for advanced SIP message tracing and troubleshooting.
- AI-Enhanced Troubleshooting: Use AI tools like ChatGPT to analyze SIP debug outputs, interpret call traces, and streamline troubleshooting processes.
- DevOps with Cisco CUBE: Apply AI to create Ansible scripts for automating Cisco Session Border Controller (CUBE) deployments, integrating DevOps practices into collaboration environments.
- Hands-On URI Call Routing: Explore the advanced configuration of SIP URI dialing, enabling efficient call routing across CUCM clusters and Cisco CUBEs.
- SIP Troubleshooting Tools and Techniques: Gain expertise in leveraging diagnostic tools like Wireshark and TranslatorX to debug and analyze SIP traces effectively.
- Foundations for Webex Calling on CUBE: Gain an overview of the key concepts involved in using CUBE as a local gateway for Webex Calling.
The course starts by analyzing SIP Request and Response messages, including the role and purpose of SDP offers and answers. Topics such as SIP early offer and early media are covered, with practical insights into the behavior and capabilities of CUCM SIP trunks. Participants will explore headers within SIP messages, along with best practices for configuring SIP profiles on CUCM for both trunk and endpoint configurations.
The course continues with SIP URI dialing, where participants learn to use ILS, GDPR, and SME servers for dynamic dial plan distribution. Labs introduce advanced CUBE topics, including the use of E.164 pattern maps, server groups, and URI call routing for optimizing call handling. Participants will also implement Voice Translation Profiles and Dial Peer Groups, along with Provisioning Policies to streamline outbound dial-peer selection.
Throughout the course, participants will engage in real-world troubleshooting labs using Wireshark, RTMT, and TranslatorX, learning how to analyze SIP debugs and traces. A final lab challenges participants to implement an end-to-end SIP solution across multiple CUCM clusters and Cisco CUBEs, mirroring real-world deployments and problem-solving scenarios.
