ITU-T T.38 (2010) Amd. 1 (10/2014)

新附录VI，澄清和纠错

ITU-T T.38建议书定义了除公共交换电话网（PSTN）或综合业务数字网（ISDN）外，在终端之间使用的部分传输路径内（包含互联网等IP网络），允许3类传真在终端之间使用传输适用的规程。此建议书的修订澄清了ITU-T H.323建议书、ITU-T H.248.1建议书、会话启动协议（SIP）和会话说明协议（SDP）的呼叫建立，并改善了ITU-T T.38网关与3类传真间的兼容性。
ITU-T T.38 (2010/09)建议书的修正1引入了更多内容以及对该建议书的更正，并增加了第11款“安全考虑”和附录VI“从历史角度看待安全性”。此外，修正1从‘实施方指南’（05/2012）和ITU-T T.38 (09/2010)建议书的勘误1（04/2013）中摘取了内容。
