  • ACD: You can view the Average Call Duration (ACD) for the route here.

Buy

Buyers configure their equipment to send traffic to the exchange. They buy traffic by placing bids. Bids depend on price and quality. In this section of Crossbow Exchange, you will be able to not only view your bids so far but place new bids as well.

In order to simplify participation in trading for users willing to buy many destinations, Bid-less routing feature is implemented in Crossbow Exchange. It allows to route any call received on Crossbow Exchange to route to the cheapest destination in case when there is no bid placed. This saves a lot of manual work to enter a massive amount of bids.

As you can see from the figure, there are two rows showing the length of the calls for every month. Each row shows the information for half of the month. The reason for showing information in such a way is that billing cycle is set as bi-monthly. Therefore cycles start on 1st and 16th of each month. However, Crossbow Exchange also allows to change the billing cycle according to your requirements.
