Session Border controllers

Nextone.

Other Devices
Expand Networks have the Expand IP Accelerator which allows IP data from many applications to
be compressed across a point to point link, allowing more bandwidth for VoIP data. They can
also provide QoS marking of data to prioritise various types of information.
Bandwidth management routers allow bandwidth to be reserved for VoIP.
