15.6.3 Quality of Service (QoS)
Quality of Service (QoS) refers to both a network's ability to deliver data with minimum
delay, and the networking methods used to provide bandwidth for real-time multimedia
applications.
Type of Service (ToS)
Network traffic can be classified by setting the ToS (Type of Service) values at the data source
(for example, at the LTE Device) so a server can decide the best method of delivery, that is the
least cost, fastest route and so on.

ports, you may need to subscribe to the services from your VoIP service provider.
The Flash Key
Flashing means to press the hook for a short period of time (a few hundred milliseconds)
before releasing it. On newer telephones, there should be a "flash" key (button) that generates
the signal electronically. If the flash key is not available, you can tap (press and immediately
release) the hook by hand to achieve the same effect. However, using the flash key is
preferred since the timing is much more precise. With manual tapping, if the duration is too
long, it may be interpreted as hanging up by the LTE Device.
You can invoke all the supplementary services by using the flash key.
Europe Type Supplementary Phone Services
This section describes how to use supplementary phone services with the
Europe Type Call

Command time-out (2 seconds) expires or issue an invalid sub-Command, the current
operation will be aborted.
