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 IP Phone.
When suppression of DTMF playback is disabled, and you dial a number or press a speeddial
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.
