IP shuffling
IP shuffling is the ability to set up a call path between two IP endpoints by rerouting the voice channel away from the usual TDM bus connection and creating a direct IP-to-IP connection. IP shuffling saves resources like TDM bus time slots and media channels and improve voice quality by eliminating unnecessary codec conversions. To enable IP shuffling there must be at least one common codec between the two point-to-point IP endpoints. IP shuffling can take place not only inside of a system but also between multiple systems. This ability is particularly useful in  a multi site call center environment where customer calls can be transferred from one person to another multiple times within the same transaction. IP shuffling will tear down each call leg and re-establish a point-to-point connection with the new calling party each time the call gets transferred, saving valuable system resources. IP Shuffling across systems. IP shuffling is particularly useful in a multi call center environment. In this example, the customer establishes a call to a call center in Berlin, Germany.
