Operational Features
Suppressing DTMF Playback
A feature on the IP phones allows users and administrators to enable or disable the 
suppression of DTMF playback when a number is dialed from the softkeys and 
programmable keys. 
When suppression of DTMF playback is disabled, and you press a softkey or 
programmable 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 much faster.
DTMF playback suppression is disabled by default. Suppressing DTMF playback 
can be configured using the Aastra Web UI and the configuration files.

Use the following procedures to configure the suppression of DTMF playback on
