Secure a Session

If an application does not want any interference by outside events for a session from TAPI or the service provider, it should secure the call. For example, in an analog environment call-waiting tones can destroy a fax or modem session on the original call.

An application can secure a call at the time the call is made or after the call already exists.

Not all service providers support use of this operation.
