Answering machine detection (AMD) is supported by the Activate utility. You supply a set of Name,Value pairs separated by semicolons as an AmdParameters property in your InstalledDialerTypes collection. Each Name is displayed in the Parameter list. The Values are default values that are displayed in the Value column when the Parameter is displayed. An empty Value can be used to indicate no default.

The AmdParameters chosen by the user are copied to the AmdParameters Project property, which is available to your dialing provider as an AmdParameters Interview property. If no AmdParameters are chosen, this is an empty string. Your dialer documentation should describe these parameters.
