Jun 09, 2015 · AES 256 Encryption Support for TLS and SIP SRTP. Cisco Collaboration Solutions use Transport Layer Security (TLS) and Secure Real-time Transport Protocol (SRTP) for signaling and media encryption. Currently, Advanced Encryption Standard (AES) with a 128-bit encryption key is used as the encryption cipher.

Sep 26, 2019 · Cisco IOS MGCP Gateway Encryption. Unified Communications Manager supports gateways that use the MGCP SRTP package, which the gateway uses to encrypt and decrypt packets over a secure RTP connection. The information that gets exchanged during call setup determines whether the gateway uses SRTP for a call.

Version 4.1.0 introduced SIP/TLS + SRTP support. The easiest way to setup encryption is to use our zero-touch provisioning as recommended settings will be set for you. When using encryption you have the choice of encrypting both signalling and media or only signalling. Specific phones can be excluded phones by editing the phone and setting encryption to ‘off’ in the phone (encryption tab).

Jul 02, 2014 · SRTP and TLS. After the endpoints (IP Phones) are secure, CUCM can establish TLS with the endpoints, and the endpoints can negotiate SRTP among themselves. Cisco voice gateways also support encryption as follows: MGCP gateway with SRTP package and IPsec tunnel to CUCM (or default gateway device for CUCM).

Call Encryption is a method of encrypting both your VoIP SIP traffic (The handshake that introduces and closes a call) and your actual VoIP Audio, often referred to as RTP traffic. We support turning on both TLS (Transport Layer Security) to encrypt your VoIP SIP traffic and turning on encryption for your RTP traffic to make the actual audio secure using SRTP (Secure RTP).

Dec 22, 2017 · Re: CUC: SIP/TLS - Encryption security mode is not supported on this version of Connection For info : CUC-PLM-ENC-K9 and LIC-UC-ENC are the same license for Encryption , so if you already have this installed on your PLM you can still activate encryption on Unity Connection without the need for LIC-UC-ENC.

A key derivation function is used to derive the different keys used in a crypto context (SRTP and SRTCP encryption keys and salts, SRTP and SRTCP authentication keys) from one single master key in a cryptographically secure way. Thus, the key management protocol needs to exchange only one master key, all the necessary session keys are generated by applying the key derivation function.
