Offhook
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 needs to be entered
here. The HandyTone ATA will automatically append the “@” and the host portion of the
corresponding SIP address.
Note: Please write down the IP address of the ATA if you use this feature as it will disable the
IVR and the only way to access it is via web configuration page.

Default is Yes. Call Forwarding & Do-Not-Disturb are supported locally
Disable Call Waiting
Default is No. User can use * code to use this feature per call basis.
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
