Query regarding to media related parameters

[Mohit]

Hi friends,

I have a query regarding to media related parameters in LINEDEVCAPS structure.

I have a case where, my TSP is not supporting any media related operations,
i.e., no MSP or wave drivers are provided with TSP.

Now, what I want to ask is, what value does TSP should fill in the media
related parameters of the LINEDEVCAPS structure when TSPI_lineGetDevCaps() is
called by TAPI?

The media related parameters in the LINEDEVCAPS structure are, dwBearerMode,
dwMaxRate, dwMediaModes, dwGenerateToneModes, dwGenerateToneMaxNumFreq,
dwGenerateDigitModes, dwMonitorToneMaxNumFreq, etc.

Should TSP fill the normal values or it should fill NULL or any other
specific value for such case?

Thanks,
Mohit

Mohit,
if your TSP doesn't support any Generate/Monitor Tone/Digits feautures the
set all thos mebers to zero.
If you don't support any data communication then the Rate members are
irrelevant and should be set to zero too.

But anyway you need to set
dwBearerModes=x1, VOICE
dwMediaModes=x4, INTERACTIVEVOICE
if your telephony device is something like a normal phone, i.e. being used
to have the usual intercative voice communication.

Thanks Andreas for your reply.

Can you tell me that from where can I find the hex values of the relevent
TSPI _constants?

Thanks
Mohit

I have one more query regarding to your reply.

You had mentioned that if my service provider is not supporitng any media
related operations, then I had to set the media related parameter values as
0. So, this 0 is 0x00(NULL) or ASCII 0(zero)?

Thnaks,
Mohit

Mohit, you are welcome.

I guess you are refering to those:
>> dwBearerModes=x1, VOICE
>> dwMediaModes=x4, INTERACTIVEVOICE

They are defined in TAPI.H / TSPI.H.
Additionally see MSDN.

Mohit,
it is 0 = 0x00 = NULL.
