DTMF Mode Control how the X6004 handles the tones that the IP phones on your
network make when they push their buttons. One use of the tones is to
distinguish between numbers when trying to dial a PSTN phone
number. You should use the same mode as your VoIP service provider.
The choices are:
• rfc2833 - Follow the RFC 2833 standard and send the DTMF tones
in RTP packets.
• inband - Send the DTMF tones in the voice data stream. This works
best when you are using a codec that does not use compression (like
G.711). Codecs that use compression (like G.729) can distort the
tones.
• info - Send the DTMF tones in SIP messages.
Privacy Select Disable to display caller ID as displayed in this screen’s
