Ultimate Power
Howler Screamer™ integrates into your soft-switch and VoIP applications as easily as our highly successful Howlets product, but augments your system with a PCI-Express acceleration card so as not to impact your CPU when doing signal processing such as transcoding.
Howler Screamer™ G.729a (Concurrent Calls)
Howler's ultra-fast G.729a codec enables you to transcode over 425 concurrent G.729/G.729a-G.711 calls when paired with the Howler Screamer™ accelerator card, enabling cost-effective transcoding of Low Bit-Rate codecs with minimal impact on your host CPU.
Tested to over half a million simulated call minutes, and bit-accurate with the reference ITU-T implementation, it provides robust acceleration for your chosen soft-switch, great quality (100dB PSNR) and is substantially more scalable than competing G.729a off-load solutions for Asterisk, FreeSWITCH and CallWeaver.
Notably, Howler is the first to offer a fully interoperable and indemnified G.729a solution in both software and hardware for FreeSWITCH, coupled with its unique floating license model for cost-effective multi-server deployments on Linux and Windows.
G.729a Howler Screamer™ for Asterisk – Dual-Core AMD Opteron @ 1.8ghz, Linux
The 1.8ghz Dual-Core Opteron Asterisk system augmented with a Howler Screamer™ PCI-E card, and our G.729a codec was able to achieve 425 concurrent calls at only 133% CPU utilisation (of a possible 200% due to the two cores), terminating to a streaming wave file of spoken words. Voice quality of the two additional calls was excellent, with no degradation in quality compared to the reference codec and immediate call connection.
