Digium TC400B Transcorder Card

VoIP Transcoding PCI 3.3/5.0V card for 120 G.729a or 92 mixed channels of G.729a/G.723.1

The TC400B is a bundle of the half-length, low-profile PCI-2.2 compliant TC400P base card and the TC400M voice processing module. The TC400B is designed to handle, in dedicated DSP resources, the complex codec translations for highly compressed audio as would otherwise be processed by Asterisk in software.
