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 enabled by default. Suppressing DTMF playback can be
configured using the Aastra Web UI and the configuration files.
Configuring Suppression of DTMF Playback
Use the following procedures to configure the suppression of DTMF playback on the IP phone.
Configuration Files
For specific parameters you can set in the configuration files, see Appendix A, the section, “Suppress DTMF
Playback Setting” on page A-181.
