Howler targets the IP PBX market with Howler Screamer, a ½ length PCI Express card with the capacity for up to
425 simultaneous G.729 transcoded calls.

London, UK. Nov 24th, 2009 Howler Technologies today announced it has launched the first in a series of high
performance telecoms products for the IP PBX and Voip market. Howler Screamer is a high-capacity transcoding
card that has over 3 times more transcoding power than any other PCI Express product currently available.

“Our Screamer-based products are designed to turbo-charge IP telecoms networks”, stated Mike Vieyra, CEO of
Howler Technologies. “By offering a huge step change in the level of performance we aim to give IP PBX users
functionality that to date has been either unavailable to them or very expensive to implement. Our Howler
Screamer products will make compute-intensive signal processing tasks accessible and affordable to the IP PBX
market”.

Howler Screamer can process up to 425 simultaneous G.729 calls and is compatible with many popular
softswitches such as Asterisk and Freeswitch. This equates to an increase in performance of 300% over
competing solutions with the same form factor. In addition, because Howler Screamer does not rely on specialist
Digital Signal Processing (DSP) hardware, customers can configure their Screamer cards according to their
business requirements and upgrade their transcoding capacity whenever they like.
Many business-class IP telephones and VoIP gateways now offer support for G.729 (a high quality, low bit rate
codec that saves on bandwidth). Historically, G.729 has been difficult for IP telecoms operators to offer because
of the costly compute resources required to transcode it at the edge of their networks. Offloading computeintensive
signal processing tasks like transcoding to a PCI card can boost the performance of an IP PBX by an
order of magnitude. The ability to optimise transcoding between G.729 and G.711 codecs means IP telecoms
operators can rationalise their infrastructure as well as create more opportunities for revenue by routing Voip
traffic directly to and from bandwidth-constrained locations.
Howler Screamer is available to buy from the Howler web store at www.howlertech.com/buy/ Per channel prices
are as low as £3.99. For more details go to www.howlertech.com
