VoiceProfile

The VoiceProfile entry is used by Unimodem to determine the voice modem capabilities of a modem.

Format

A single command string of type DWORD.

Examples

The following two examples demonstrate the use of this entry.


    HKR,, VoiceProfile,    1 , 07,a1,02,02
Or:    HKR,, VoiceProfile,    1, 27,03,00,02


    HKR,, VoiceProfile,    1, 25,12,00,02

Remarks

The ProCalc tool should be used to create the voice profile entry. For more information about ProCalc, see Creating Voice Modem INF File Entries with ProCalc.

The bits in the VoiceProfile DWORD are set as follows:

DescriptionBit value

Identifies a voice modem (should always be set).

0x00000001

Modem has some element of a TAPI phone device. For example, it can play audio to the handset or report handset hookswitch events.

0x00000200

Speakerphone state must be reset after recording from line.

0x00000400

Speakerphone state must be reset after playing from line.

0x00000800

0x00002000

If distinctive ringing is enabled, the first ring reported by modem may not be correct. Unimodem will not report the first ring. (This is not supported in Windows 2000 and later versions.)

0x00004000

Modem does not report the first ring when distinctive ringing is enabled. (This is not supported in Windows 2000 and later versions.)

0x00008000

The modem reports silence DLE.

0x00010000

Modem does not support DTMF generation while in voice mode.

0x00020000

Modem does not monitor DTMF digits while in voice mode.

0x00040000

UART baud rate is set before issuing StartPlay or StartRecord commands. If this bit is not set, UART baud rate is set after the StartPlay or StartRecord command.

0x00080000

UART baud rate is reset after the StopPlay or StopRecord command is issued.

0x00100000

Modem keeps handset disconnected from modem while in voice mode. If this bit is set, Unimodem displays "Talk/Drop" dialog during outgoing calls. Unimodem will not allow the line to be opened as Owner/InteractiveVoice.

Note  VOICEPROF_SET_BAUD_BEFORE_WAVE 0x00080000

This bit indicates the DTE should adjust the baud rate before issuing the StartPlay/StartRecord commands. If the bit is disabled or cleared, then the baud rate will be adjusted after these commands are issued. Usually this bit is set for Rockwell chipset modems.

Distinctive Ring is not supported by Windows 2000 and later versions, therefore the bit value of 0x00001000 is required.

The VoiceProfile bit (0x02000000) is for Windows 2000 and later versions of the operating system. This bit must also be used in conjunction with the following voice entries that are specific to Windows 2000 and later versions of the operating system:

BaudRate (NT Wavedriver)

XformModule (NT Wavedriver)

WaveHardwareID (NT Wavedriver)

WaveDevices (NT Wavedriver)
