Rotary telephone.Day In the Life of a VoIP Phone Call

In “A day in the life of a VoIP phone call,” walk packets in a phone call through routers, ethernet switches, T1 links, firewalls, SBCs, etc., The purposes are: (a) to introduce the purpose of the different components covered in the IP Foundations class, and (b) to introduce SIP, MGCP and RTP. Learn how all of the layers of the network work together to produce a working call.

This is a 1/2 Day Module.

VoIP Systems Design

Overview of all of the considerations in building or upgrading VoIP carrier networks, including mapping services to systems, CPE selection, network transmission capacity planning (Mbps), switching capacity planning (PPS), security requirements, end-to-end product testing, billing, etc.

This is a 1 Day Module.

Prerequisites: VoIP Call Control & Troubleshooting

IMS Overview

This module is an overview of IMS covering practical engineering aspects. How does IMS differ from standard Carrier VoIP? In what cases is IMS Compliance beneficial? This module cuts through the hype to identify the real business opportunities and technical realities for Services Providers.

This is a 1/2 Day Module.

VoIP over 3G/4G Wireless

Many wireless service providers offer wireless high-speed data services. As the network capacity and the Over-The-Air latency drops for 3G/4G data services, VoIP over 3G/4G is becoming a reality, and may displace conventional CDMA or GSM call control. This module covers the state of the industry for VoIP over 3G/4G, and explains a technical architecture to accomplish VoIP over 3G/4G.

This is a 1/2 Day Module.

VoIP CPE Management

SIP Phones and IADs have complex software and configuration files. Manually configuring them is impractical and labor-intensive. Effective CPE Management can make the difference between successful, reliable operation and unreliable, expensive services. This module describes the challenges of CPE Management, and describes effective technical approaches to managing CPE through centralized configuration. We cover the BroadWorks IP Device Management system, and cover Configuration Management for PolyCom, Aastra, Linksys, and Cisco phones in detail. We also review distribute approaches, including the EdgeWater CPE management system.

This is a 1.5 Day Module.

Prerequisites: VoIP Call Control & Troubleshooting

VoIP Security

VoIP networks are subject to attacks that were impossible on SS7 networks. We cover the key attacks and failure conditions. We show how un-protected networks are subject to attackers can interrupt service, steal confidentiality (such as recording phone calls), steal service, overload the system, retrieve customer data, etc. We include US Federal government requirements for Customer Proprietary Network Information (CPNI). And we show how to defend your network against VoIP network attacks.

SIP for Engineers and Technicians: Part II

This 2 Day module covers advanced SIP calling and feature scenarios, including:

  • Call Transfers
  • Busy Lamp Field
  • Shared Line Appearance / Shared Call Appearance
  • Message Waiting Indicator
  • SIP over TCP
  • SIP Connect
  • Feature Key Synchronization
  • N-Way Conference Calling

This is a 2 Day Module.

Monitoring and Fault Detection

RJ45/Cat5 Computer Cables Chaotically Plugged Into Cross Connect Panel

VoIP Carrier networks are complex. Every network includes numerous vendors; monitoring and detection includes SNMP traps, monitoring, syslog monitoring, and other tools. How do you know what to monitor? How can you identify future problems before your customers do? This course covers effective techniques for taming the data feed to understand the health of the system and quickly identify problems. We cover SNMP polling and traps, syslog, and use Zenoss to introduce network monitoring. The information in this course can be applied to other systems such as HP OpenView and IBM Tivoli NetCool.

This is a 1 Day Module.

Prerequisites: IP Foundations for VoIP Carriers

Acme Packet SBC 3000/4000/9000 principles for Peering and Hosted NAT Traversal — 1 day

This is a high-speed boot camp for real world configuration and management on the Acme Packet SBC. We avoid theoretical issues and show time-tested, battle-proven techniques for Acme Packet SBC configuration. Participants in the course learn how to boot an SD from scratch, configure Hosted NAT Traversal (used for IP PBX / Centrex) and SIP Trunking / Peering.

This is a 1 Day Module.

Prerequisites: VoIP Call Control & Troubleshooting

VoIP Network Performance Analysis

VoIP Networks have stringent requirements — far more rigorous than ISP networks. How do you keep your VoIP network in top performance? This module shows how to analyze your network to identify performance problems. We cover Ethernet switches, Routers, TDM interfaces, Acme Packet SBC, SIP and MGCP performance. Participants learn to analyze packet queueing, congestion, drops, CPU issues, memory issues, and spurious SIP/MGCP signaling.

This is a 1 Day Module.

Prerequisites: IP Foundations for VoIP Carriers

Unix & Log Analysis for VoIP/BroadWorks system Administrators

This module is focused on BroadWorks service providers. We introduce Unix basics, show how to move an manipulate files. We also study the BroadWorks logs on the BroadSoft Application Server, Network Server, and Media Server to identify call problems, and assess system behavior. We study statistical measurements output by BroadWorks to understand system load issues.

This is a 1 Day Module.

VoIP Capacity planning and Forecasting

VoIP network capacity planning is complicated by the richness of features. A system that supports 20,000 basic residential users may only support 5,000 users with enhanced business features. To properly set prices for your features, you must understand the workload of each feature. How do you predict system capacity requirements ? How do you know if your system is approaching overload? How do you engineer capacity for new subscribers when features like N-Way Conference Calling are used? We cover Media (RTP), Signaling management, and Capacity planning for fault tolerance.
