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 signalling 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.
¤
Enable
Audio
or
RFC 2833
if DTMF signals are to be transmitted acoustically (in
voice packets).
¤
Enable
SIP Info
if DTMF signals are to be transmitted as code.
Enabling the G.722 wideband telephony codec on the DECT network
Both parties involved in a phone connection (caller/sender and recipient) must use the
same voice codec. The voice codec is negotiated between the sender and the recipient
when establishing a connection.
The G.722 codec (wideband connection) enables high voice quality, but only a maximum
of four simultaneous connections per base station.
¤
Enable the G.722 codec to permit wideband transmission for all handsets on the DECT
network.
