Additional Features
Additional Features
This section describes additional features you can use on the 57i CT phone.
Star Codes
All of the main call handling and extension management features for your system can
be set up as speed dials on softkeys on your phone. Contact your System
Administrator for more information about available star code functions in your
network.
If these have not been set up, you can dial any star code commands on the 57i CT
phone the same way you would on a regular telephone.
Suppressing DTMF Playback
A feature on the IP phones allows you to enable or disable the suppression of DTMF
playback when a number is dialed from the softkeys.
When suppression of DTMF playback is disabled, and you press a softkey, the IP
phone dials the stored number and displays each digit as dialed in the LCD window.
When the suppression of DTMF playback is enabled, the IP phone dials the stored
number and displays the entire number immediately in the LCD window, allowing
the call to be dialed faster.
DTMF playback suppression is disabled by default. Suppressing DTMF playback
can be configured using the Aastra Web UI.
