For a start, the fastest and easiest fix to this that will work no matter what is retries. Any time a user is expected to enter something(an ID number, to select a menu option, etc), when they fail to do so (so, on a Get TT String, the step goes down the TIMEOUT path), run a retry routine. See the sample applications in TeleFlow for examples. Refer to MenuSet and MenuMan flowcharts. These, when used anywhere a user input is required, will ultimately hang up when a user is not longer on the line, regardless of hang up detection.
- Ideally, the lines you are using should be set up with hang up supervision. They should be configured to cause a disconnect by a loop current drop when a caller hangs up.
- You will need to use the Set Reorder Tone step and Enable Reorder steps to enable reorder connection. The reorder parameters in the Set Reorder Tone step must be set up to match the reorder tones provided on the lines.
Note that there is no guarantee that reorder detection will work. This is why we recommend the retries solution to this problem.
