Auto-Dial This parameter allows a user to configure a User ID or extension number to be
automatically dialed upon offhook. Please note that only the user part of a SIP address

the host portion of the corresponding SIP address.

Disable Call Waiting Default is No.
Send DTMF
This parameter controls the way DTMF events are transmitted. There are 3 ways: in
audio which means DTMF is combined in audio signal (not very reliable with low-bit-
rate codec), via RTP (RFC2833), or via SIP INFO.
DTMF Payload Type This parameter sets the payload type for DTMF using RFC2833
Send Flash Event This parameter allows a user to control whether to send an SIP NOTIFY message
indicating the Flash event, or just to switch to the voice channel when the user presses
the Flash key.
FXS Impedance Selects the impedance of the analog telephone connected to the Phone port.
NTP server This parameter defines the URI or IP address of the NTP server which the HandyTone
ATA will use to display the current date/time.
Send Anonymous
If this parameter is set to “Yes”, the “From” header in outgoing INVITE message will be
set to anonymous, essentially blocking the Caller ID from displaying.
Lock keypad update If this parameter is set to “Yes”, the configuration update via keypad is disabled.
WAN side http
access If this parameter is set to “No”, the HTML configuration update via WAN port is
disabled.
