You can achieve this by developing a converged application that USES the SIP protocol to communicate with the next-generation network and HTTP to access legacy protocols.
为此，可以开发一种聚合应用程序，使用SIP协议与下一代网络通信，使用HTTP访问旧协议。

We created a service wrapper which uses the WebSphere MQ protocol to connect to that legacy application.
我们创建一个服务封装器，其使用 WebSphere MQ 协议与以前的应用程序相连。

Another inevitable case is when you have to deal with a legacy proprietary protocol to ensure the interoperability with an old system.
