EP-44SIP(H) WEBSERVER
Secure Real‐Time Transport Protocol (SRTP) is a protocol that allows encryption of RTP data. Since
the RTP encryption key is delivered over SIP, this feature is only relevant when the SIP transport is
secure, so when you use this feature, you will also need to use SIP over TLS.
Enable SRTP Encryption and Authentication: Enable or Disable SRTP.
Method: You can select three SRTP encryption method: AES_CM_128_HMAC_SHA1_32,
AES_CM_128_HMAC_SHA1_80 or AES_CM_128_ALL_METHODS
ARIA: Enable or Disable the ARIA cipher Algorithm [RFC5794] and its use with SRTP.
Configure the SRTP parameters and then click Submit.
