Using telephones
Fixed telephones connected to the FCT telephone line
work in the same way as if they were connected to a
fixed network.
Warning!: you will not be able to make or receive
data or fax calls while a speech call is ongoing.
Note: you can also benefit from some FCT
functionality that you do not usually have on your
fixed network. See “Advanced features” on page 22.
You can find detailed information about the tones that
the FCT sends on Audible tones page 36.
