Retention of telephone conversations and their file format

This is an interesting issue that I am looking to address. How long should telephone conversations be kept?

A data protection principle is that information should be kept for no longer than necessary.

RM principles suggest you maintain records dependent upon their content/function for as long as is required. These principles are format independent so you do not look to apply the same one size fits all rule to a "format". For instance we do not keep all emails for x period of time, if the email is a contractual arrangement - it is kept as a contract record. An email about arranging a lunch is not kept beyond the event, it can be deleted straight away.

The same should be applied to phone recordings but if it is not possible to do classify calls, what should be done? It looks like a one-size fits all approach will have to be taken - 1 year, 6 months, 30 days - what fits best?

File format is interesting as well, in this instance .WAV files are generated - wouldn't an MP3 be more open and accessible, particularly for those who do not operate Windows systems?
