The Digium’s TC400B is a device used specifically as a voice compression card. It is dedicated to resolving highly complex codec translations for compressed audio. It is basically a bundle of half-length, low profile PCI 2.2 card that is generally used with Asterisk software to provide more robust and easy network connectivity. The device helps a lot in relieving CPU of its duty and freeing it up to handle other tasks. It will help to decompress G.729a (8 kilobits) or G.723.1 (5.2 kilobits) data into a compressed form.

• It helps to reduce bandwidth consumption by a factor of 8.
• It supports large number calls from a narrow-band connection.
• It helps to reduce loads or extra work from CPU.
• The device can handle up to 120 bi-directional G.729a transformations or 92 bi-directional G.723.1.
• One of its features also includes Codec Licensing and Indemnification.
