EM770 voice function with VB

[baobui]

hello every one,

I have a EM770 module with the voice function activated.In the device manager, theree are 2 port of this module: UI port and Application port. If I use the mobil partner software, the voice call is OK. I use the serial monitor sofware to monitor the 3G Application port and I can see the voice data come to the mobilpartner software when I make a voice call.

Now, I want to write my own application to make voice call with the EM770 using VB. I can open the UI port and send AT command to dial to another phone, but I can not get any data in the 3G Application port. I tried all the hand shake scheme (none/xon-off/hardware) but have no luck. The AT commands I send are the same as the AT commands that the mobil partner software sends.

Please can any one tell me how to get the voice data out of the EM770 module?

Thank you very much

You can activate voice feature by dc-unlocker software.
You will need to use mobile partner software version that support voice feature.
