PJSIP version 2.5 is released with support for Opus and WebRTC AEC

PJSIP version 2.5 is released with main focus on Opus codec and WebRTC AEC integrations. The PJSIP bundled libsrtp package has also been upgraded to version 1.5.4 which brings a higher level of media security via AES-256 crypto suites.

As usual the release also includes several enhancements and bug fixes, please see the Release Notes page for more info and grab the source code from the Download page.

WebRTC Acoustic Echo Cancellation on PJSIP

Echo, unless you’re in a karaoke pub, is very annoying.

Over the years we have added support for various echo suppression and cancellation algorithm and libraries, like Speex and bdIMAD.

WebRTC, besides being a communications protocol on its own right, contains a powerful media component which in turn contains, among other things, acoustic echo cancellation algorithm implementation.

Try pjsip using WebRTC AEC on the development code by following the usage notes.

Eventually this will form part of 2.5 release (before you ask, no, we don’t have a definite timeframe for it).
