Use powerful performance of 32-bit network processor and voice signal Processes of DSP which are special-purpose for network. The performance, the sound quality and the stability are much more competitive with the other low cost of VoIP SoC.
Nowadays, there are many VoIP devices, specially for low-end products of 1 to 2 ports gateways, which use special-purpose SoC (System On Chip) applied by CPU with DSP on the same chip or not use DSP to execute voice compression, echo cancellation and so on by main CPU's processing ability only.
The soft CODEC is used instead of DSP that this kind of product's price is lower as to reduce the use of components, but the performance is limited as the cost down of hardware, and as a result that the most end products are produced by Turn Key's program provided by chips' suppliers that just can provide simple function and become very difficult to produce customized products or debug program.
ALLWIN's entire OneInGate VoIP series used specific powerful performance of 32-bit network processor and voice signal processes of DSP according to different deployments' devices no matter for 1 port of TA, IP phone, E1 trunk gateway.
Therefore the performance, the sound quality and the stability are much more competitive with the other low cost of VoIPs' devices.
