#1 In Vista

SipxAudioGetNumInputDevices(m_Instance.InstanceHandle, NumberOfDevices) -- there doesn't seem to be a library to Enumerate Input/Output Devices. May have to use a hack found at:
http://www.codeproject.com/KB/cs/Enum_Recording_Devices.aspx

Ran it in Vista Enterprise -- broke at SipxMedia.vb:
If type = SipxMediaDeviceType.Input Then
--> MySipxResult = SipxAudioGetInputDevice(m_Instance.InstanceHandle, i, DeviceName)

"An unhandled exception of type 'System.AccessViolationException' occurred in SipXTapiDotNet.dll
