Interviews via telephone can be successfully recorded, however it pays to be aware of certain issues, in order to avoid having an annoying 'hum' the entire way through your recording.

We suggest keeping the following in mind:

• Try to avoid recording via your speakerphone - the sound quality can be extremely variable. Specialised telephone recording devices are relatively inexpensive (between $30 and $90). Some of these devices plug into your telephone while others insert into the Dictaphone itself, so consider what will best suit your circumstances.
• Try to avoid using cordless phones (and never ever use a cellphone), as interference can be introduced into the recording.
• If a cordless phone is the only option, try to keep your distance from anything that may cause interference, e.g. microwaves, wireless networks, cellphones and baby monitors.
• If using a DECT phone, try to use one within the 1.9GHz range - these tend to block out more interference.
• Try installing a filter on your telephone line (especially if you have ADSL). These are relatively inexpensive and can be purchased from your local electronics store.
• Temporarily disable call waiting for the duration of the interview - information on how you can do this can be obtained from your telecommunications provider.

Something else to keep in mind with telephone interviews is that you can't see the person's facial expressions or body language. Novice interviewers have a tendency to make "encouraging noises" (e.g. uh-huh, yeah, I see what you mean). These are absolutely fine, but try not to talk over top of the person you're interviewing. As you'll be nearer the recording device than they are, it will be your comments that are heard as opposed to them.
