Voice Aware Mobility

• Voice Awareness is now also built into the Aruba Mobility algorithm.

• When a device on call moves from one controller to another, a tunnel is

established across the 2 controllers with the traffic being tunneled back to the

HA to ensure that the session awareness and security is not compromised by

the move.

• Once the call is disconnected, the new controller takes over as the HA for the

device

This controller is

the HA for the

device on call

This controller is

the HA for the

device on call

All new calls are

routed directly out

of the new HA

1/As the device on call moves, the

HA remains the same to ensure

security and session awareness

2/When the call disconnects, the

new controller takes over as HA

The client’s IP address will also

change if the move is a L3 move
