Some points must be taken into consideration when using SRTP to transport T.38 fax over IP traffic. Encryption keys will need to be exchanged through some key management protocol outside of the T.38 transmission, such as ZRTP or MIKEY. According to RFC 4612, fax payloads should not use an HMAC-SHA1 authentication tag shorter than 80 bits.

This technical white paper is a practical guide for applying SRTP to voice, fax, and other IP telephony media. It is intended for engineers and gives an overview of IP telephony security and technical fundamentals of SRTP. Network administrators can use this paper to learn how to configure SRTP and SDP security services for various purposes.

2024年10月4日 · SRTP（Secure Real-time Transport Protocol）是一种用于保护实时通信数据的网络协议。它主要用于音频和视频通信，以确保数据的机密性和完整性。SRTP是在RTP（Real-time Transport Protocol）的基础上开发的，RTP是一种用于实时传输媒体数据的协议，但不提供安 …

2024年8月31日 · Secure Real-time Transport Protocol (SRTP) 是一个专为实时传输协议（RTP）设计的安全配置文件，旨在为音视频会议等单播或多播应用中的RTP数据提供加密、消息认证以及完整性保护和重放攻击防护。 SRTP由Cisco和Ericsson的互联网协议及密码学专家团队开发，并于2004年由IETF以RFC 3711发布。 它支持高级加密标准 (AES)作为默认密码，并提供了多种操作模式，包括分段整数计数器模式来实现流加密。 此外，SRTP允许集成如ZRTP …

2013年8月21日 · If you want SRTP to work for faxing then you should use passthrough (modem NSE based passthrough for faxing b/w cisco gateways and protocol based fax pass-through for interop b/w cisco and another PBX/vendor). Cisco fax relay also supports SRTP for faxing but it is out dated and not supported on ISR G2 routers.---

2023年5月9日 · FFmpeg可以使用SRTP（Secure Real-time Transport Protocol）来保护实时音视频流的传输安全。SRTP是一种基于RTP（Real-time Transport Protocol）的安全传输协议，它提供了加密、认证和完整性保护等安全机制，可以有效地防止音视频流被窃听、篡改和重放攻击。

Host-based Fax over IP engine that leverages field-proven fax technology to deliver high levels of performance, reliability, and scalability. Suitable for high-speed, high-density fax production environments in both enterprise data centers and hosted service provider networks.

2024年10月28日 · SRTP-RTP interworking connects RTP enterprise networks with SRTP over an external network between businesses. This provides flexible secure business-to-business communications without the need for static IPsec tunnels …

2019年3月12日 · What are some best practices for configuring T.38 Fax Relay on a VG224 analog gateway running SCCP and STCAPP? A. For any SCCP controlled analog gateway, the only method available for T.38 is an NSE-based switchover. Protocol-based switchover or standards-based switchover to T.38 is not supported with SCCP controlled endpoints.

2023年4月27日 · SRTP（Secure Real-time Transport Protocol）是一种基于RTP的加密协议，用于保护实时音视频传输中的数据安全。SRTP使用了一些加密参数算法来确保数据的机密性、完整性和认证性。 其中，SRTP加密算法包括
