摘要： A SIP communication session can be set up between at least two client SIP nodes over at least one proxy SIP node. A proxy SIP node is located based on a destination client name and domain and a secure signal connection is set up between a calling client SIP node and the proxy SIP node. The destination client IP address is located from the proxy SIP node using the destination client name and domain. An additional secure signal connection is set up from the proxy SIP node to a called client SIP node. The secure signal connection and the additional secure signal connection together form a secure signal path. The destination client SIP node is requested to return its IP address across the secure signal path. The returned IP address is used in setting up a data connection between the calling client SIP node and the destination client SIP node.

摘要翻译： 可以通过至少一个代理SIP节点在至少两个客户端SIP节点之间建立SIP通信会话。 代理SIP节点基于目的地客户端名称和域定位，并且在主叫客户端SIP节点和代理SIP节点之间建立安全信号连接。 目标客户端IP地址位于使用目标客户端名称和域的代理SIP节点。 从代理SIP节点到被叫客户端SIP节点建立附加的安全信号连接。 安全信号连接和附加的安全信号连接一起形成安全的信号路径。 请求目的地客户端SIP节点通过安全信号路径返回其IP地址。 返回的IP地址用于建立主叫客户端SIP节点与目标客户端SIP节点之间的数据连接。
