The Cloud and Voice Encryption
When the first version of pbxnsip introduced RTP encryption, it was a pioneering feature, but it didn’t generate the expected marketing success. Back then, customers were just happy if they could hear each other over VoIP. Over time, we refined our SRTP implementation to address challenges like the rollover counter, optimized transcoding, and avoided one-way audio issues. With growing awareness of security, encryption is now a critical focus, yet many providers still don’t encrypt voice traffic. To bridge this gap, we’ve added the ability to write decrypted PCAP files, making troubleshooting encrypted voice easier. This is available in version 5.1.3.
