WMI will contain all the information you need in the Win32_POTSModem class. In C# or .Net, you can utilize the System.Management namespace to query WMI. Within .Net, you can use MgmtclassGen.EXE from the platform SDK to generate a class object representing the WMI class. The command line would be like this: C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin\mgmtclassgen.exe Win32_POTSModem /L CS /P c:\POTSModem\Win32_POTSModem.cs and then

(you tell the server who you 'are' before you send the message) Is this the case with a carrier's cell tower? I guess I'm wondering what the service is called and how it works? (ie. can you send 'header info' with SMS messages or is the cell tower

Is there any Android SDk support,any version is fine for me? Plz give some inputs.. Thanks In Advance. Kevin Junghans You cannot manage a conference with a smart phone. You need an intermediate service that can do this for you. You can program a conference manager using CCXML . Voxeo has a good hosted platform for CCXML implementations and you can look at their documentation on how to setup conferencing. There are examples in
