TAPI on Windows 8 not Work ?
« on: January 20, 2015, 02:31:59 pm »
Hello.
 I'm trying to use Voice Modem with nrCommLib in Windows 8, but am not having positive results.
The system says my device is not compatible.

 But if I use AT commands directly to the modem, I can configure it to voice mode normally.

 See below:


Opened voice modem device
ATE0
OK
ATQ0V1
OK
AT&R1
OK
AT&Q3
OK
ATM2
OK
ATX4
OK

Entering voice mode
AT+FCLASS=8
OK

Initializing voice params
AT+VNH=1
OK
AT+VSD=103,50
OK
AT+VGT=153
OK
AT+VRA=45
OK
AT+VRN=25
OK

Recording voice file 'Recording.rmd'

Setting compression
AT+VSM=132,8000,0,0
OK
AT+FLO=2
OK
AT+VRX
CONNECT

<START RECORDING>
<VOICE DATA 800 bytes>
<VOICE DATA 800 bytes>
<VOICE DATA 800 bytes>
<VOICE DATA 800 bytes>
<VOICE DATA 800 bytes>
<VOICE DATA 800 bytes>
<VOICE DATA 800 bytes>
<VOICE DATA 800 bytes>
<VOICE DATA 800 bytes>
<VOICE DATA 800 bytes>
<VOICE DATA 800 bytes>
<VOICE DATA 800 bytes>....


Note: Important!

I'm testing an application: "Venta Fax & Voice 7.4 (Home version)"
It has option to use the modem or TAPI.

In the "Use TAPI" it does not work. But the option "Use Modem" works normally.
That is, there is a solution, just do not know how to do .. What use .. etc ..

Could anyone help?

Note:
Sorry, I do not speak English. I'm using google translator (tell me how was the text easy to understand?).

Hello

nrComm Lib TAPI uses voice functionality of modem as sound device.
Did you install proper sound drivers for your modem?
Do you see new sound device in Windows Device Manager?

Hi

Yes, I would use my modem as a new audio device. I do not see it in Windows 8 (only XP and Win7).
You can use nrCommLib in Win8 (using TAPI)?

Hello

If your modem supports voice functionality, the manufacturer provides sound drivers for this modem.
You need to install them and you will see new sound device in Device Manager.
After that you can try voice functions of nrComm Lib.
