RIM records all employee calls (news.zdnet.com)

I work in a regulated industry, and all our calls are recorded as a matter of course (the company is perfectly upfront about doing this, and everyone understands the reasons behind it). The tapes are only meant to be used in the case of an investigation by the regulators, but some bright spark decided to that, after a major incident, the recordings of the conf call should be analyzed to capture action points, lessons learned, etc. So we all piled into a boardroom and they started the recording... Which turned out to be several hours of people bitching and swearing, often about completely unrelated things to the incident, with pretty much no useful content (all of which had been sent by the actual engineers via IM). So we stopped doing that.

The moral of this story: recording internal calls isn't unusual and it's unlikely that anyone really cares.
