Additional Features
Suppress 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 keys on your phone.
When suppression of DTMF playback is disabled, and you press a key, 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 enabled by default. Disabling suppression of DTMF playback can
be configured using the Aastra Web UI.
Configuring Suppression of DTMF Playback
Use the following procedure to configure suppression of DTMF playback.
1. Click on Basic Settings->Preferences->General.
2. Go to the "General" section
.
3. The parameter “Suppress DTMF Playback” is enabled by default. (Disable this field by
unchecking the box). Default is enabled.
4. Click to save your settings.
