Dialing Feature Support
Automotive 7 provides the following dialing capabilities:
• Handset keypad dialing
• Speed dial
• Redial
• Digit Dialing
• DTMF
Handset Keypad Dialing
Automotive 7 lets a user dial using a connected handset. For phones that enable SCO at all times
while connected, Automotive 7 mutes the SCO line unless a call is active or incoming. This
prevents button presses from interrupting the user’s audio experience.
When a call is connected using keypad dialing or any other means that does not immediately
report the number to the Automotive 7 device, Automotive 7 attempts to obtain caller ID
information after the call is connected.
Speed Dialing
Speed dialing is available when the Bluetooth-enabled phone contains speed dial information.
When using this feature, the Automotive 7 device can use the saved speed dial information on
the paired phone to dial the phone number.
Redial
Redial functionality is provided via the HFP redial command. Redial uses the last outgoing
number stored in the Bluetooth phone. When using redial, Windows Embedded Automotive 7
attempts to obtain caller ID information after a phone call is connected.
Digit Dialing
When a Bluetooth phone is connected, digit dialing is available to the user via a manual method
through the UI, a speech method, or a combination of both, depending on an application’s
implementation.
On vehicle platforms that include buttons numbering zero through nine, the user is able to enter
digits to dial a number. A button combination allows the user to delete the last digit and clear all
entered digits.
DTMF
Automotive 7 supports DTMF tones for all numerals, including the asterisk (*) and pound sign
(#). A user can enter digits manually or by voice. The digits are sent while a call is connected.
Phone Feature Support
Automotive 7 provides support for the calling and phone features shown in Table 8.
