CounterPath desktop and mobile softphones feature the highest levels of security


Security and Encryption

As voice communications have become more vulnerable to the same type of attacks that data has endured over the past two decades, organizations are constantly trying to ensure that precautions are taken to ensure privacy and security in their communications.

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

All of CounterPath's softphones can be configured to support specific combinations of signaling and media encryption using Transport Layer Security (TLS) and Secure RTP (SRTP) protocols for encrypting both SIP messages and RTP media streams between your IP PBX, Media Gateway or UC platform and CounterPath application. These security measures greatly reduce the threat of "man in the middle" attacks that can include wiretapping, eavesdropping, or threats to the security and privacy of your softphone application. TLS provides an encrypted connection between your UC platform and CounterPath softphone, while SRTP encrypts the media.

Protocol Overview

Transport Layer Security (TLS) is a cryptographic protocol that encrypts the segments of network connections at the Application Layer for the Transport Layer, using asymmetric cryptography for key exchange, symmetric encryption for confidentiality, and message authentication codes for message integrity.

By using TLS to encrypt SIP signalling, parameters such as phone numbers and user names sent between your UC platform and CounterPath softphone application cannot be captured. TLS also helps prevent third parties from eavesdropping or tampering with messages.

Secure Real-time Transport Protocol (SRTP) defines a profile of RTP (Real-time Transport Protocol), intended to provide encryption, message authentication and integrity, and replay protection to the RTP data in both unicast and multicast applications. In essence, SRTP secures your conversations by encrypting audio and video media traffic – and even if unauthorized users were able to intercept and capture your audio packets, they would be unable to recognize it as speech.
