TAPI_E_INVALMODE
What TAPI_E_INVALMODE means
TAPI_E_INVALMODE A mode parameter is outside the set accepted by the TAPI method or by the selected service provider.
What to check
- Capture the native method and numeric mode value rather than only the symbolic wrapper value.
- Compare the value with the modes advertised for the current address, call, phone, terminal, or stream.
- Check for bitwise combinations that are individually defined but not valid together.
Handling
Choose a mode supported by that exact object and provider generation. Do not coerce an unknown mode to a default silently.
