Hyperlinked Phone Number

The user can now call a phone number from a meeting invitation on a device that runs Windows Mobile Professional. Meeting invitations commonly have a call-in phone number embedded in the body of the invitation. This functionality has been available for Windows Mobile Standard and is now available for Windows Mobile Professional. A phone number in the body of the invitation is hyperlinked and will open the Edit Before Call screen, where the user can conveniently and quickly progress to making the call. This includes a properly formatted conference call number and passcode sequences, such as 18001234567p123456#.

Speaker Phone and Mute

When the user answers an incoming phone call on a device-locked Windows ®phone, they now have access to Speaker Phone and Mute options while in the call. These two options are available from the Soft Key 2 menu. On Windows Mobile Professional, these options are available when the new Lock screen is not enabled.

In previous versions, users did not have this capability. This functionality applies to all resolutions, orientations, and supported languages. It is also in effect with the Simple PIN, Strong Alphanumeric, and Code Word screens. The Code Word screen is the screen that prompts the user to type a1b2c3 when incorrect passwords were typed more than the allowable number. The user still cannot make a call, access contacts or call history, or use other phone settings while the phone is locked.

This functionality does not apply to third-party or OEM-replaced Local Authentication Plug-ins (LAPs).


  • On devices that do not support hardware Talkand Endbuttons, you can now let the user dial emergency calls from the Local Authentication Plug-in (LAP) during the Sensitive Data Protection (SDP) process. This functionality is set in the registry and utilizes the left soft key.

  • You can now customize speed-dial behavior to prevent unintentional speed dialing when a user is in a call and wants to enter a PIN or interact with Interactive Voice Response (IVR) systems.

Other changes

  • When a Windows Mobile user is in a phone call and has a second phone call on hold, the device can now display a notification when a third call is received.

  • Push-to-talk has been integrated with Contacts, SmartDial, and Call History. You can customize menus, soft keys, dialog boxes, and other user-interface elements for better push-to-talk functionality. These features can also be used for any Session Initiation Protocol (SIP)-based services.

  • The Windows Mobile user can now record a voice call from the Call Progressdialog box. The recorded calls are stored in the same directory as the recordings the user makes in Voice Notes.

  • The user can now ignore an incoming call and automatically send a predefined SMS message as a reply to the call.

  • A Quiet beep was added for notifications and alarms while a user is in a call. Notifications and alarms are captured, and a more subtle sound will play in the user's ear instead of the default sound.

  • When the user dials and is connected to an emergency number from a simple or strong PIN-locked screen, the text "Emergency" (Windows Mobile Standard) or "Emergency Call" (Windows Mobile Professional) is displayed on the screen.

Phone Features

Silencing Notification Sounds by Using the END Key

The user can now silence all alert or notification sounds that are associated with an incoming phone call in addition to dismissing the call itself by pressing the Endkey. If you want the user to only be able to dismiss the phone call itself, and not silence the associated alert or notification sound, you can revert to the old behavior for the Endkey, that is, dismissing only the incoming call and letting the alert or notification sounds play entirely, by setting the following registry key:


Disabling Non-numeric Character Mapping on PIN Editing Controls

OEMs can now control whether non-numeric characters can be mapped to numeric values on simple PIN-edit controls by configuring the HKEY_LOCAL_MACHINE\Security\Phone\PhoneKeyMatchregistry key.

This allows OEMs to prevent users from entering non-numeric characters on simple PIN-edit controls.

Phone Network Operating Mode Settings

Phone network settings are stored in the registry HKEY_CURRENT_USER\ControlPanel\PhoneNetSelMode\Option.

Shortening the Phone Unlock Sequence

Registry value SkipKeyLockConfirmcan be set to shorten the sequence to unlock a phone.


Global Phone Support

Global Phone supports two radio types on the same device — Code Division Multiple Access (CDMA) and Global System for Mobile Communications (GSM). On a Global Phone only one radio type is active at a time but the device is able to switch between CDMA and GSM without rebooting.

Insert Country Code Menu Option

A new menu option in Windows Mobile Standard provides the ability to insert an international dialing code in the phone number being entered by selecting the code from a list.

Phone Settings Options Support

When phone settings options are displayed, they will be the GSM options if the device is registered on GSM, and the CDMA options if the phone is registered on CDMA.
