DTMF in VoIP connections
To send DTMF signals via VoIP, you must first define how key codes should be converted into and sent
as DTMF signals: as audible information via the speech channel or as a "SIP Info" message.
Ask your provider which type of DTMF transmission is supported.

You have the following options:

If you activate the option
Yes
, the phone automatically attempts to set the suitable DTMF signal-
ling type for the current codec for each call.
¤
If you disable the
No
option, you can use the other options to specify the DTMF signalling type.
