摘　　要：对Parlay APIs协议和SIP协议中与呼叫相关的部分作了对比,首先提出了两者与呼叫相关的核心概念的映射关系,列举了SIP Server工作在两种常用模式下的具体概念映射模型;随后阐述了Parlay CC API与SIP消息之间的映射,并给出实例加以说明;接着对二者的地址映射问题进行了讨论;最后给出了一个基于SIP的Par-lay CC API构建基本会话的时序关系。The parts related with call in Parlay application programming interface （Parlay APIs） and Session Initiation protocol are compared in the article. It proposes the mapping relationship of their key concept concerned to call, and specializes the two con- crete mapping model which SIP Server works on the mode in common use. And then the paper illustrates the mapping of message be- tween Parlay CA2 API and SIP, and gives an example about these messages. Afterward, the issue of address mapping has been dis- cussed. Finally an application sequence diagram using Parlay CC API base on SIP is drawn.
