Part 1 - The Basics

(morning)

• Overview of Voice over IP and IP Telephony
• Components of an IP Telephony Solution
• Advantages of an IP Telephony Solution –How it can save you money and increase efficiencies to your company.
• Avaya IP Telephony Architecture
• Primary Call Servers
• H.248 Gateways
• Critical Components of an IP Telephony Solution Explained:
  • C-LAN
  • MedPro
  • IPSI (SIPI)
• The equivalent components in an H.248 gateway described
• Digital Signal Processors (DSPs) – what they are and why you need them for VoIP
• Reliability options described in detail for the S87x0
• Enterprise Survivable Servers (ESS)
• Local Survivable Processors (LSP)
• Standard Local Survivability (SLS)
• IP Phones and H.248 Gateway registration points
  • C-LAN
  • Processor Ethernet
  • How they are different and what you need to know to make the right decision
  • How using Processor Ethernet can create an “all IP configuration” with the need for those IPSI connected port networks.
• Wireless IP Phone Options
• Endpoints – SIP, H.323 – considerations for when to use SIP and H.323
• Mobility – One-X Mobile (aka Extension to Cellular – EC500)
• SIP – What is it? Separating the Hype from Reality
  • What you need to know about SIP to help you today.
  • What will SIP do for us in the future?
• Do I really need to “SIP Enable” my network?
• SIP Trunking – What you need to know to successfully deploy SIP trunking
• SIP Adjunct Servers – How to successfully integrate Avaya and 3rd party SIP products into Avaya Communication Manager
• Why FTP and NTP are important services to integrate into your IP Telephony Solution.

Part 2 - Beyond the Basics: Design, Implement and Troubleshoot

(afternoon)

• How The IP Telephone Works – DHCP, TFTP/HTTP, ACM Registration Overview
• Virtual LANS (V-LANs)
  • What they are and why you want to separate voice and data using V-LANs
  • Native V-LAN and Tagged V-LANs – What they are and how this relates to a Converged Network
• How to configure your network to allow an Avaya IP Phone to self discover the Voice VLAN to ease and speed IP Phone deployment
• Details of a VoIP Conversation
  • TCP for control
  • UDP for voice
• Shuffling and Hair Pinning explained
  • Yes, you can shuffle calls between H.323 and SIP endpoints.
• WAN choices
  • Point-to-Point
  • VPN over the Internet
  • VPLS and MPLS – What there are and why it is an increasingly important component of my IP Telephony solution
• What you need to know to implement Avaya IP Telephony over an MPLS network, a best practices approach.
  • QoS
• H.248 Gateway Configuration Settings explained
  • MGC list
  • MGC timers
  • How the ACM’s Link Lost Recovery Timer is used with these H.248 settings
  • Real customer problems when these values are not set correctly.
• Data Switch Port Speeds and Duplex Settings
  • When to use Auto Negotiate and when you should lock downs those ports.
• Quality of Service – Layer 2 and Layer 3 QoS. What it is and why it is critical to IP Telephony and VoIP deployments
• Different QoS implementation methodologies
  • Trust model
  • ACL model
  • What is the difference
  • Why would I use one over the other
• QoS techniques discussed – LLQ, etc.
• Call Admission Control (CAC)
  • What is it and why do I need it
• Inter-gateway Alternate Routing (IGAR) explained
• What it is and why you want to use this feature

  • Know your topology!
  • What they are and how they can make you multi-site
  • IP Telephony solutions hum with efficiency. 
  • Virtual Network Regions – How they complete your Network Region Design
  • Call Admission Control (CAC)
  • A real life customer example of not using Network Regions properly - How it might work fine the night to the cutover and why it will fail under load when everyone come intowork on Monday.

  • C-LAN Load Balancing
  • Alternate Gatekeeper Lists (AGLs) explained
  • 176/242 DHCP Strings Explained and how they are used
  • Why you need to use DHCP to ensure IP Telephone registration to the LSP
  • How to size your AGLs for quick failover to the LSP
  • A real life customer example of what can happen if your AGL is too large.
• Disaster Recovery (DR) and Business Continuity (BC) options and planning
  • Detailed description of various DR configurations
