IP Trans-coding
The system employs either the IEEE g.711, g.729 or g.723 codec to digitize and compress
voice signals for RTP packets between devices. IP Phone or terminals on DTIM/SLTM
incorporate DSP functions to support codec conversion Available VOIBs include DSP circuitry
used to support trans-coding (converting) codecs for incoming VoIP calls to devices.
The VOIBs will trans-code the incoming voice codec (g.711, g.723, g.729) to the System codec
and reverse the process for outgoing packets. When the external VoIP connection can only
support g.729 and the system codec is g.723, the DSP must implement a complex trans-coding
operation, which requires 2 DSP channels. In all other cases, trans-coding only requires a
single channel per call.
