TRANSCRIPT

  • 1. Enhanced Communication Server (ECS)Ver. 5.5 IntroductionJanuary 2008

2. Lesson Objective At the end of this lesson, the participant will be familiar with the ECS functionality and capabilities 3. Enhanced Communication Server (ECS) - Overview

  • Manages IP telephony and multimedia communication network including:
    • MCUs
    • Gateways
    • Endpoints
  • ECS acts as a Zone Manager and performs:
    • Internal and external policy management
    • Phone book management
    • Call management
    • Monitoring and statistics

4. Supports

  • All standards compliant H.323 Endpoints
  • Anything supporting H.323 v2 and higher
  • Gateways
  • MCUs

ECS H.323 XML Radius LDAP HTTP 5. Agenda

  • ECS Registration Features
  • Managing Calls Features
  • Network Topology
  • Additional Features

6. Policies

  • Internal policies
  • External policies

ECS Registration Call initiation (admission) Registration Authentication Server Call Authorization Server 7. Phone Book Management - Address Translation Bill Bob 192.114.36.202 192.114.36.202 Bob Address Translation Table 8. Phone Book Management Registration Policies

  • Policy: Who can register?
    • Internal Policy
      • License capacity limitations
      • Configurable capacity limitations
      • Predefined endpoint management
      • Registration restrictions
    • External Policy
      • LDAP server authentication
      • Radius server authentication
  • Keep Alive
    • Lightweight registration
    • IRQ

9. Call Management Registration Policies

  • Call establishment and control
  • Policy: Who can call?
    • Internal
      • License capacity limitations
      • Configurable capacity limitations
      • Policy manager
        • Groups
        • Bandwidth
    • External
      • Authorization servers

10. Groups

  • Set identical service levels
  • Allow/prevent initiating calls
  • Allow/prevent receiving calls
  • Allow a single set of services
  • Set maximum bandwidth to/from endpoint

11. Authorization - Summary

  • A user is trying to make a call (Admission request):
    • Internal:
      • EP registered tothe ECS
      • Groups limitations
        • Receive and make calls
        • Service
        • Bandwidth
      • Subzone and interzone rules limitations
    • External Authorization Server

12. User Authentication Using External Server LDAP Server Reg Request Reg Request Reject/Confirm Reject/Confirm 13. Agenda

  • ECS Registration Features
  • Managing Calls Features
  • Network Topology
  • Additional Features

14. Managing calls

  • Address translation
  • Routing modes
  • Authorization server (XML API)
  • Redirection rules (forwarding/fallback)
  • Dialing policies (conference hunting, line hunting, group hunting)
  • Bandwidth policy (groups and sub-zones)
  • Billing (CDRs)
  • 3 rdparty call control (XML API)

15. Call Routing Policies

    • Internal
      • Configurable routing mode
        • Direct
        • Call Setup (Q.931)
        • Call Setup and Call control (H.245)
        • Firewall Traversal (RTP)
      • Forwarding and fallback
      • Services
        • Line hunting
        • Conference hunting
        • Group hunting

16. Call Management Make Call

  • Administrator initiated call establishment (H.245 mode)

ECS Side A Side B 17. Routing Mode

  • Basic management
  • Hierarchy
  • Registration authentication
  • Call authorization
  • Alternate GK
  • Bandwidth policy
  • Limited forwarding and fallback
  • Limited billing
  • Improved billing
  • Complete forwarding and fallback
  • Line, conference, group hunting
  • Additional billing information
  • Make call
  • Firewall traversal

Monitoring and Statistics

  • Summary and details of registrations and calls
  • Event log and SNMP traps
  • CDR files for billing
  • Application logs

22. Event Log 23. Agenda

  • ECS Registration Features
  • Managing Calls Features
  • Network Topology
  • Additional Features

24. Network Topology

  • Configure multiple gatekeepers in a network structure:
  • Flat topology- neighboring gatekeepers
  • Hierarchical network Consists of Parent and Child Gatekeepers
  • ECS can neighbor to any standard Gatekeeper.

25. Hierarchical Network Middle Level Child ECS knows only Parent Lowest Level Regional GKs, call routing, GWs and MCUs

  • Scalable and modular
  • Fault resilient
  • Expandable
  • Manageable
