The lower the price, the least cost routing mechanism in our Porta VoIP Switch will pick the lowest cost routes. This limits the number of carriers than can connect your call. This may result in lower Average Call Duration (ACD) and Answer Seize Ratio (ASR) for certain international destinations. So in the VoIP business, the higher the cost, better the route, as you will have multiple redundant carriers for each destination .
For international destinations, our premium routes will allow multiple redundant carriers to same destinations.
