If you have an interrupted dial tone, but no 1571 voice mail message waiting, it is likely that a caller has hung up after the call has connected, but before the message recording has started.
These steps will remove the interrupted dial tone:
- Call your number and leave a message when prompted
- Dial 1571 and delete the message
Note: Activating Call Diversion on your line will also cause a 'stuttered' dial tone. To find out how to check for this, visit How do I divert calls from my phone?.
