Why do I not get an interrupted dialtone on landline voicemail?

[John127]

My voicemail was reinstated, however the biggest feature "Interrrupted Dialtone" was not there when I tested it. Is this an error, or is normal?

You are not receiving the interrupted dial tone when you have a message waiting?
