SIP APPLICATION SERVERS What is a SIP Application Server ? –A network entity that speaks SIP –AND IS PROGRAMMABLE !!!

Technologies - CPL http: //www. ietf. org/rfc 3880. html • CPL stands for CALL PROCESSING LANGUAGE • XML call behaviour scripting • Protocol Agnostic • Loaded and executed in a container • Allows basic (non interactive) predefined modification of call behaviour based on time criteria, address criteria or network signalling criteria • With CPL you can do things like “forward all my calls to voicemail if I’m not available, the caller is my girlfriend and is Friday” • Open. SER provides CPL implementation module

Technologies – SIP CGI http: //www. ietf. org/rfc 3050. txt • Defines a communication channel between the SIP server and the application scripts. • Applications scripts (CGIs) can be written in any language. • Similar in spirit to the invocation of external applications in Open. SER via 'exec' module

Technologies – OTHERS CCXML - Call Control XML • Scriptable, XML based • Protocol agnostic • Supports variables and dynamic script retrieval Jain SLEE – Service Logic Execution Environment • Protocol Agnostic • Event driven • Applications defined as a composition of components

SIP SERVLET JAVA API!! JUST LIKE SIP INHERITS PART OF ITS BEHAVIOUR FROM HTTP, SIP SERVLET PROGRAMMING IS SIMILAR TO HTTP SERVLET PROGRAMMING DEFINED IN JAVA COMMUNITY STANDARD JSR 116 NEW VERSION 1. 1 DEFINED IN JSR 289 COMING SOON

SIP SERVLET PROGRAMMING MODEL SIP SERVLET APPLICATIONS CONSIST OF SERVLETS RUNNING INSIDE A SERVLET CONTAINER

SIP SERVLET PROGRAMMING MODEL SERVLETS ARE WRITTEN IN JAVA AND TRIGGERED UPON RECEPTION OF REQUESTS AND RESPONSES

SIP SERVLET PROGRAMMING MODEL SERVLETS ARE WRITTEN BY THE PROGRAMMER TO IMPLEMENT BUSINESS LOGIC WITH LOW PROTOCOL KNOWLEDGE REQUIRED PROGRAMMERS USE CONTAINER RESOURCES SIP Resources Message creation reception and delivery Transaction Managemet Dialog Management Parallel/Sequential Proxying J 2 EE JNDI Resources Database Pooling Resource references Environment entries

SIP SERVLET PROGRAMMING MODEL MANY CONTAINERS SUPPORT CONVERGENCE APPLICATIONS HANDLE SIP AND HTTP MESSAGES HTTP SESSIONS CAN SEE/INTERACT WITH SIP SESSIONS AND VICEVERSA
