Yes, there is a service provided by making a (free) call to
17070. Listen to the menu offered and select either "quiet line" or "ring back", as appropriate.
If your telephony service is via a LLU provider (e.g. TalkTalk), you will only hear the announcement of the number associated with the line. To perform either a "quiet line" test or a "ring back", you would need to make a (chargeable) call to
020 87599036.
From my notes, this is what you would hear --
"This circuit is defined as nnnnnnnnnnn.
Welcome to your Openreach line test facilities.
Press- for ring back.
- for quiet line.
- for fast test.
- for fast cleanse.
or clear down."
