IMS Based Session Initiation Protocol in Robot Framework for Telephony Services

IMS is a standard architectural framework which is used for the purpose of delivering multimedia communications services such as voice, video and text messaging over IP networks. IMS architecture has been sub-divided into number of network components or elements which each does its own distinct job in the network, standardized interfaces it follows to promote scalability, flexibility and extensibility. The Session Initiation Protocol or it can be called as SIP is used for establishing the sessions, modifying the sessions, and termination the sessions. The SIP protocol is designed for the purpose of providing the independent services for the underlying transport protocol, so SIP applications can run over TCP, UDP, or TLS or any other network protocols. The paper introduces with what is robot framework basically and how it is connected to IMS and how it uses an standard protocol Session Initiation Protocol for telephony services. Robot framework is used for functional testing building the devices to work end-to-end. The framework uses an approach keyword driven for the purpose of writing the scripts and after the execution of the scripts the it will be stored in log files and displayed in from html page.
