Analysing the System

• Service Creation
• Dial plan (Apache-like configuration)?
• AGI (programming scripts) i.e. bash, Java, C, etc
  ..
• SER configuration (combo of prog lang and
  UNIX-like config file format)?
• Asterisk Application API (C only)?
• Tight coupling of services and control layer

Next Generation Networks

• Definition A Next Generation Networks (NGN) is
  a packet-based network able to provide
  Telecommunication Services to users and able to
  make use of multiple broadband, QoS-enabled
  transport technologies and in which
  service-related functions are independent of the
  underlying transport-related technologies. It
  enables unfettered access for users to networks
  and to competing service providers and services
  of their choice. It supports generalised mobility
  which will allow consistent and ubiquitous
  provision of services to users. ITU-T
  Recommendation Y.2001 (12/2004) - General
  overview of NGN

JAIN SIP Applet Phone An example JAIN System

• Origins
• Born out of JAIN SIP Initiative
• Developed by NIST labs
• Open source Java softphone based on JAIN SIP 1.2
  API
• Planned Extensions
• Video services
• Interop testing
• Customisation for inhouse projects

JAIN SLEE and JAIN APIs

• JAIN Service Logic and Execution Environment
• Defines component model for structuring
  applications through reusable OO components
