Back to the top

A RAS client attempted to connect to your server and the connection was interrupted before the specified number of rings for the RAS or RRAS server could occur.

For example, you have your server configured to answer after five rings. A client dials and the call is interrupted before it reaches the fifth ring. The server will not answer any more calls on that port until the RAS or RRAS server is restarted.
