Agenda

• VoIP Landscape
• SIP with J2EE
• Use Case Audio/Video conferencing application

4
IMS

• IP Multimedia Subsystems
• Next generation mobile specification
• SIP as the signaling protocol
• Driver for Fixed / Mobile / IP Convergence
• Cutting edge services
• Increase ARPU
• Telephony applications and services look more
  like HTTP applications

5
VoIP Overview

• Signaling plane
• SIP Application Servers
• Session Setup
• Session Management
• Session teardown

• Media Plane
• Media Servers
• Control and processing of real-time multimedia
  data

SIP

• Session Initiation Protocol
• Base Protocol ? IETF RFC 3261
• Leading Signaling Protocol for VoIP development
• Create, Modify and Teardown Multimedia Sessions
• Mobility
• Event Subscription / Notification
• Presence
• IM

7
Media Servers

• Essential to Multimedia Applications
• Controlled via Media Gateway Control Protocols
• Mature Standards
• MGCP
• MEGACO H.248
• Standardized as IMS Media Gateway Control
  Protocol
• Recently Introduced
• MSCML
• MSML/MOML

8
MSCML Overview

• Media Server Control Markup Language
• XML based
• Transported over SIP messages
• INVITE transactions
• INFO transactions
• APIs
• Create / Terminate Conference
• Add / Remove Conference Participant
• Modify Conference Leg
• Play / Record Announcement
• Collect DTMF Digits
• etc

9
VoIP Applications

• VoIP enables an extensive new set of applications
  and revolutionaizes some of the traditional
  services like
• Softswitches
• Voice Mail
• Push to Talk
• Voice and Video Conferencing
• Application Sharing
• IVR
• etc

10
Challenges on SIP App Development

• SIP and MEGACO / MGCP Stacks

• Build
• High Development Cost
• High Maintenance Cost
• Buy
• Vendor Specific Interfaces
• Complex Integration
• Maintenance

11
Challenges on SIP App Development

• Application Platform
• C/C ? Intrinsic Platform Dependency
• HW / OS platforms
• Development Environment
• OS abstraction layer

• Build
• High Development Cost
• High Maintenance Cost

• Buy
• Cost
• Vendor Specific Interfaces
• Complex Integration
• Limited OS Support

12
Challenges on SIP App Development

• User Management Interfaces
• Complex Integration with Application
• Application Scalability
• Architecture
• Testing
• Application Fault Tolerance
• Architecture
• Testing

13
Challenges on SIP App Development

• Integration with other applications
• Databases
• Web Services
• Enterprise Information Systems
• Reusability
• No resources to create reusable components
• New Application ? Same Challenges

Agenda

• VoIP Landscape
• SIP with J2EE
• Use Case Audio/Video conferencing

15
What does J2EE provide for VoIP?

• JSR 116 SIP Servlet container
• J2EE Framework
• Web-tier Servlets, JSP
• Infrastructure JDBC, JNDI, JMS, JTA, JTS, JAAS,
  Mail, JMX
• Business-tier JavaBeans, EJB
• Integration RMI, JRMP, IIOP, J2EE-CA, Web
  Services
• J2EE Application servers
• Clustering, Replication, High Availability,
  Failover
• Integrated Security, Management
• Platform independence
• Enhanced development and deployment tools
• Technologies around J2EE (Struts, JSF, Spring, )

J2EE Advantages

• Fusion of cutting edge communications technology
  and proven enterprise reliability
• Simplified SIP handling using SIP Servlets
• Natural convergence of web-tier with business
  tier
• Standards based infrastructure
• Easy integration with back-end applications
• XML Automation
• Support for Workflow
• Support for heterogeneous environments
• Availability of tools and solutions around J2EE
• Cost of development, deployment and maintenance

SOA for VoIP Services

• Expose SIP servlet features as generic,
  re-useable web services
• Create composite services by orchestrating low
  level granular SIP features
• Expose services to Enterprise Service Bus
• Implement complex VoIP applications using
  composite services
• Quick turnaround from concept to deployment of
  services

21
Modularization Extensibility using SOA

• Java web services can be used to modularize SIP
  features
• Web service modules are re-useable and generic
• VoIP applications can be extended easily using
  service orchestration by adding additional
  services

Agenda

• VoIP Landscape
• SIP with J2EE
• Use Case Audio/Video conferencing

24
Use case Audio/Video Conferencing

• Service provider offers conferencing service
• Conference host schedules a conference with
  conferees
• Conferees get notified of conference via e-mail
  or SMS, accepts/denies participation
• Host and conferees receive call at time of
  conference
• Conferees enter PIN, record name to join the
  conference
• Conferees switches video on/off
• Host Manages Conference
• Extend/Terminate Conference
• Remove Conferees
• Mute / Unmute Conferees
