但我们确实不能负担将每个请求的扩展都直接构建到处理器中的任务；那将会形成一个有许多不常用功能的巨型库。

But we really can't afford to build every requested extension directly into the processor; we'd wind up with a huge library of infrequently-used features.

接下来，我们将构建SIP INVITE请求，并将其发送到第一台服务器。

Next, we can build the SIP INVITE request and send it to the first server.
