    • A Session Initiation Protocol (SIP) server comprises a signaling data system that receives a first SIP message having a Session Description Protocol (SDP) data set. The signaling system responsively stores the SDP data set in association with a session segment identifier and transfers a session request having the session segment identifier and not the SDP data set. The SIP server has a session data system that receives the session request having the session segment identifier and not the SDP data set. The session data system responsively authorizes the session request and transfers a session instruction having the session segment identifier. The signaling data system receives the session instruction having the session segment identifier and responsively identifies the SDP data set with the session segment identifier and transfers a second SIP message having the SDP data set.
    • 会话发起协议(SIP)服务器包括接收具有会话描述协议(SDP)数据集的第一SIP消息的信令数据系统。 信令系统响应地存储与会话段标识符相关联的SDP数据集,并传送具有会话段标识符而不是SDP数据集的会话请求。 SIP服务器具有接收具有会话段标识符而不是SDP数据集的会话请求的会话数据系统。 会话数据系统响应地授权会话请求并传送具有会话段标识符的会话指令。 信令数据系统接收具有会话段标识符的会话指令,并响应地识别具有会话段标识符的SDP数据集,并传送具有SDP数据集的第二SIP消息。
