mustardman Posted September 6, 2007 Author Report Share Posted September 6, 2007 chinese software What does that mean? Does it adhere to any standards? In my experience Echo is the most troublesome and most overlooked aspect of software based PBX's so I need to know more details to make a proper decision about the product.

Vodia PBX Posted September 6, 2007 Report Share Posted September 6, 2007 Nono. If you open the box you will see that the chipset actually is mindspeed (www.mindspeed.com). They provide the audio subsystem (they have their own DSP unit for this on the chip!), and AFAIK they sold truckloads of these chips already. The problem with FXO is finding the right gain, and once that is done echo compensation is not such a big problem. We upgraded our software to the 2084 version and so far echo was reasonable.

So there is no echo cancellation? Quote Link to comment Share on other sites More sharing options...
