TAPI_E_CALLNOTSELECTED
What TAPI_E_CALLNOTSELECTED means
TAPI_E_CALLNOTSELECTED The operation requires a selected call, but the specified call is not currently selected.
What to check
- Capture the call identity and the selection set immediately before the failing method.
- Check whether a UI selection changed asynchronously or the call left the list after disconnect.
- Verify that the selected call object belongs to the same address/provider instance as the operation.
Handling
Select a live call explicitly and repeat the operation against that call. Avoid retaining UI selection state after call teardown.
