Secure media

Overview

Enfonica supports secure media by encrypting call audio using SRTP.

Making secure calls from Enfonica

To make secure calls from Enfonica, specify the secure=true parameter in your SIP URIs. When this parameter is configured, outgoing calls will require SRTP encrypted call audio.

If you don't specify secure=true but do use transport=tls, Enfonica will offer SRTP but not require it.

When Enfonica offers SRTP, it will offer all supported ciphers below.

Receiving secure calls to Enfonica

To receive secure calls when making calls to Enfonica, include SAVP in your SDP offer. If SAVP is specified with a supported cipher, Enfonica will select the first supported cipher.

Supported ciphers

Enfonica supports the following ciphers:

  • AES_CM_256_HMAC_SHA1_80
  • AES_CM_128_HMAC_SHA1_80
  • AES_CM_256_HMAC_SHA1_32
  • AES_CM_128_HMAC_SHA1_32
