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 24.

You can find detailed information about the tones that

the FCT sends on Audible tones page 38.
