Introducing Screamer
Enable high transcoding capacity at low cost. You can choose how many G.729 calls you need on your Screamer Card and whenever you want more, just upgrade, no need to install new hardware. Screamer is designed to offload the complex codec translations for highly compressed audio that would otherwise need to be processed by your telephony platform in software.

The Howler Screamer PCI Express card is available now and can be ordered from our web store. It’s a low profile, ½ length cell processor card that is flexible and upgradable. Howler's unique floating license model allows you to run G.729 transcoding across multiple cards in your network for load balancing and redundancy.

Transcoding complex codec’s like G.729 requires a substantial amount of CPU overhead that can severely hamper the performance of your soft-switch. Screamer completely relieves the CPU of this duty, freeing it up to handle other tasks or complete additional call processing.

Howler Screamer decompresses G.729a (8.0kbit) into G.711 u-law or a-law; or compresses G.711 u-law or a-law into G.729a. Its compatible with leading 32-bit & 64-bit soft-switches. A windows API interface is also now available.

Howler Screamer G.729 codecs  are fully indemnified and do not require additional royalty fees to be paid. It's all included!
