Send Telephone Events via
RFC2833 signalling using
payload value
When enabled, the Gateway will send RFC2833
frames for the Telephony events (see also
Enable
Keypad Events)
.
Consult your Call server documentation to know if
this RFC2833 option is supported and what Payload
value is required.
The default payload value is 96.
Enable Keypad Events (0-9, *, #)
This option enables sending the DTMF digits 0-9,*,#.
By default, DTMF sending is disabled.
Suppress voice packets during
RFC2833 Telephone Event
packet transmission
Enabling this option preserves the original voice
bandwidth and prevents the need for more bandwidth
for the RFC2833 packets. Consult your Call server
documentation for the preferred mode of operation.
Squelch inband DTMF audio
To enable outband DTMF select this option.
Play DTMF received via RFC2833
To enable playing DTMF tones received via RFC
2833 events.
ABCD event signalling mode
Two possible modes for RFC2833 Telephony events
signaling (ABCD signaling packets) are available:
Transition
mode: In this mode, the event packet is
sent only at the moment of the event.
Continuous
mode: In this mode, the event packet is
sent continuously at the rate of the voice, as long
as the event exists.
The Continuous mode behaves better in situations of
packet loss, preventing cases such as stuck ringers.
Consult your Call server documentation for the
preferred mode of operation.
