Switching back and forth between two calls. You can accept incoming calls even
though you are already making a call, or have an enquiry call with other participants
involved in the call.
USB
Stands for "Universal Serial Bus," a fast serial interface with a transfer rate of up to
12 Mbit/s. A (theoretical) maximum of 127 devices can be operated on a single USB
interface, and the devices can be plugged in or unplugged while the computer is still
running.
User-to-user signalling (UUS)
User-to user signalling enables the exchange of messages between devices via the
data channel while the call is being established or cleared down. One of the main
areas in which this is used is data communication. UUS enables password queries or
automatic query routines from host to client computers.
