Filter Out Incoming DTMF Events
In Release 3.2.2, an Administrator can now enter a parameter in the configuration files
to suppress incoming DTMF playback. This new parameter called “
suppress incom-
ing dtmf playback
” will suppress the playback of both SIP INFO and RFC2833 incom-
ing DTMF tones. The locally generated DTMF tones will still be played.
Configuring Suppress Incoming DTMF Playback
Use the following parameters to suppress incoming DTMF playback:
Send DTMF for Remapping Conference or Redial Key
Previously, the “Conf” and “Redial” keys could be mapped to a speed dial to generate
a call to a custom number when the phone was idle. During an active call, pressing
the “Redial” or “Conf” keys would put the current call on hold and then dial the cus-
tom number. Now the “Conf” and “Redial” key remappings have the same behavior as
the “Speed Dial” key when the phone is idle. During an active call the phone will send
the custom number as DTMF using the phone configured DTMF method (inbound vs
out-of-band RFC2833 vs SIP INFO).
This feature can be configured using the new “
map redial as dtmf
” and “
map conf as
dtmf
” parameters.
