Abstract: This invention concerns architecture for a SIP stack that enables the addition or removal of new services without this having any impact on the other part of the stack. The user agent class contains sessions, the session class contain transactions and service implementations, while the transaction class simply contains service implementations. The user-agent class is programmed to retrieve session service implementations from the application and to attach them to session instances. The session class is programmed to receive transaction service implementations from the application, via the user agent class and to attach them to transaction instances. The proposed architecture allows an application to simultaneously support more than one version of a specific service. Added benefits also include making the customization process of these services quite easy.

Abstract translation: 本发明涉及用于SIP堆栈的架构，其能够添加或移除新服务，而不会对堆栈的其他部分产生任何影响。 用户代理类包含会话，会话类包含事务和服务实现，而事务类只包含服务实现。 用户代理类被编程为从应用程序检索会话服务实现，并将它们附加到会话实例。 会话类被编程为通过用户代理类从应用程序接收事务服务实现，并将它们附加到事务实例。 所提出的架构允许应用程序同时支持多个版本的特定服务。 增加的好处还包括使这些服务的定制过程非常简单。
