VMG's phone ports, you may need to subscribe to the services from your VoIP service
provider.

22.10.2.1 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 VMG.
You can invoke all the supplementary services by using the flash key.

22.10.2.2 Europe Type Supplementary Phone Services

This section describes how to use supplementary phone services with the Europe Type Call Service
Mode. Commands for supplementary services are listed in the table below.
After pressing the flash key, if you do not issue the sub-command before the default sub-command
timeout (2 seconds) expires or issue an invalid sub-command, the current operation will be aborted.
