2.14 Receiving interphony calls
You can answer a call without lifting the handset. When you receive a call, you are automatically
connected in hands-free mode. The identity of the caller is displayed on the screen. This feature
depends on the system configuration. If necessary, contact your administrator.
To activate
• (in idle state): corresponding LED lights up (blue). The key remains lit as long as the
interphony is not deactivated.
When your caller hangs up, interphony mode remains active.
To deactivate
• (in idle state): the corresponding LED goes out.
Interphony can be disabled by the administrator.
2.15 Sending DTMF signals
DTMF (Dual-Tone Multi-Frequency) or FV (Fréquence Vocale) signalling is a system whereby audible
tones are used to represent buttons on a keyboard and allows communication with interactive
voice servers.
During a conversation you sometimes have to send DTMF signals, such as with a voice server, an
automated attendant or a remotely consulted answering machine.
Depending on the system configuration, the DTMF can be activated by default.
If DTMF is not activated by default on your system:
• During a conversation.
• Send DTMF
• Enter DTMF code.
The function is automatically cancelled when you hang up.
If DTMF is activated by default on your system:
• During a conversation.
• Enter DTMF code.
If DTMF is activated by default on your system, you have to deactivate DTMF before entering the
code of a feature: Deactivate DTMF (Deact DTMF).
