You can now book a no-charge telephone conference bridge that also allows you to record at no charge. FreeConferenceCall.com is now offering this service.
Just submit your name and email and they will assign a phone number and code which will be good for 120 days. You will get a returned teleconference number, PIN number and instructions. There will be a separate PIN for host recording. For playback, you call into a different number and PIN to listen to the recording, and to download it as a WAV file, RSS feed, or in podcast format. Just a note that you cannot save more than one recording at a time – your next call will over write the previous call.
