  • Patent number: 10078635
    Abstract: System, methods, and computer program products are provided for configuring a computing system that processes messages according to the Session Initiation Protocol (SIP). The method includes defining, by a scripting-type computer processing language, one or more variables, where each variable is configured to store state data based on at least a portion of a SIP message and is associated with the SIP message flow. Once configuration is complete, a series of SIP messages belonging to the SIP message flow is received by the computer system. As each SIP message in the series is received, each SIP message is processed where the message processing includes modifying the state data stored in at least one of the variables based on data included in the respective SIP message.

  • Patent number: 10033770
    Abstract: Systems, methods, and computer program products are provided for modifying a Session Initiation Protocol (SIP) messages. The method includes providing a scripting-type computer programming language that includes contexts that reference pre-defined portions of data of a SIP message and variables that store data associated with a SIP message flow. An interface for configuring rules to be executed when processing SIP messages is provided. Each rule includes an action that describes a modification to be made to a particular SIP message. When a SIP message is received, it is parsed to determine at least a context of a portion of the message. The parsing includes associating the portion of the message with a particular context. It is then determined whether a rule should be applied to the data associated referenced by the contexts, and if so, the SIP message is modified based on the actions associated with the rule.

  • Patent number: 9894104
    Abstract: Systems, methods, and computer program products are provided for providing context through a scripting-type programming language to data included in a SIP message. The method includes defining one or more contexts through a scripting-type computer programming language. The one or more contexts reference a particular pre-defined portion of a SIP message and are provided by the scripting-type computer programming language. A series of SIP messages may then be received, where each SIP message in the series belongs to the same SIP message flow. After a particular SIP message in the series is received, the message is parsed to identify whether it includes any portion of data that can be referenced via one or more contexts. Any particular portion of data that can be referenced via a context is associated with a respective context such that the respective portion of data can be referenced by the context.
