Security and Encryption

CounterPath's Bria and eyeBeam softphones provide the ability to set up various configurations of security for incoming and outgoing calls - from more relaxed (try for secured but fall back to unsecured if secured is not possible) - to less relaxed (allow only secure calls, or refuse all secure calls).

Bria and eyeBeam can be configured to support specific combinations of signaling and media encryption (security). Signaling encryption is possible only using TLS as the transport; UDP and TCP do not support signaling encryption. Media encryption, which is performed using SRTP, can only be supported if signaling encryption is in place, in other words, if TLS is used for the transport.

The type of encryption supported is constrained by the type of transport offered.

In addition to signaling and media encryption via TLS and SRTP streams, CounterPath offers optional integration of ZRTP into its softphones and solutions. ZRTP is a new protocol that achieves risk-free security without reliance on a PKI (Public Key Infrastructure), key certification, trust models, certificate authorities or key management complexity. It performs its key agreements and key management in a pure peer-to-peer manner over the RTP packet stream and interoperates with any standard SIP phone.
