Ofcom
has explained the SPL and TSL condition in an explanatory
guide. We have extracted the following:
1. You should make every reasonable effort to inform all
parties to a call that it may or will be recorded, silently
monitored or intruded into. It is up to you how you do this
and that acceptable options, depending on circumstances,
might include:
–
Warning tones
–
Pre-recorded messages
–
Spoken
warnings by the operator
–
Written warnings included in publicity material, telephone
directories, contracts etc.
2. It may not always be possible to warn first time
callers with whom you have had no previous contact but what
is important is that you have a systematic procedure in
place, which provides the necessary information where this
is a realistic possibility.
3. Ofcom also suggest following on a ruling from the
European Court of Human Rights that staff are told of a
phone that they can call from which will not be recorded.
