G.729 Howlet

Optimised audio codecs for Asterisk, FreeSWITCH & Callweaver

Our G.729 software codec includes patent royalties and is optimised to work on the leading softswitch platforms. It's GPLv2 compliant and compatible with 32-bit & 64-bit processors.

Introducing G.729 Howlets
logoThe G.729 Codec is an industry standard algorithm that compresses and decompresses a digital audio stream. Applied to Voice over IP (VoIP) calls, G.729 compresses the audio data to use significantly less network bandwidth than a standard or uncompressed VoIP call.

Instead of the 64kbit/s required for a standard, uncompressed G.711 PCM audio data stream, the G.729 codec compresses the payload to 8kbit/s.This compression allows for more calls to be carried without increasing network capacity and allows voice to travel on limited-bandwidth connections that would otherwise not support VoIP.

Our Howlet release delivers a high-performance G.729A implementation and ships as a drop-in binary module for ease of deployment. It is compatible with Asterisk, FreeSWITCH, CallWeaver, Elastix, Trixbox and Switchbox.

As well as substantially improved scalability, our embedded and distributed license manager allows for flexible licensing options, including our unique Floating License which allows you to pool channel licenses across several servers on a network segment. Howler is the only company to offer patented G.729 codecs for FreeSWITCH & Callweaver. We also have an API interface for companies that want to integrate our codec implementation with their proprietary softswitch.
