How to Record Voicemail Messages

Recording your existing voicemails is a great way to save important messages. There are many ways to record your voicemails ranging from simple to more advanced methods. Here are a few options to consider:

Consider recording important voicemail messages directly to your Smartphone, computer, or recording device (cassette player, Mp3 or iPod). To improve the sound quality, consider purchasing a telephone recording adapter available online and at retail stores.. You can also record directly to your cell phone or computer, using the built-in or external microphone.

To record using a telephone recording adapter:

  1. Plug your telephone handset into the recording adapter handset jack and plug the other end of the adapter into the telephone handset jack
  2. Plug the 3.5mm recording adapter audio jack into your recording device (cassette player, Mp3, iPod). Note: 3.5mm audio jacks do not fit most cell phones, which typically use a 2.5mm jack
  3. Set the switch on the recording adapter to the "Record" position
  4. Access your own voicemail by following the prompts and dialing the keypad as instructed
  5. Begin listening to your messages
  6. Record the voicemail message by pressing record on your recording device
  7. Press stop recording when finished

To record using a computer or cell phone and microphone:

  1. Connect a microphone to your computer or cell phone, or use the built in microphone, and place it next to your telephone speaker
  2. Access your recording program (e.g. Sound Recorder located in Windows>Accessories, Voice Memos located in iPhone>Utilities, etc.)
  3. Place your telephone on "speaker"
  4. Access your own voicemail by following the prompts and dialing the keypad as instructed
  5. Begin listening to your messages

For the More Tech Savvy

To record using a PC calling program like Skype or Google Voice:

  1. Download and install a PC calling program like Skype or Google Voice and / or a call recording program
    • Note: The remaining instructions in this section pertain to Google Voice; however most online calling or recording programs offer similar functionality
  2. Setup your contact numbers in your Google Voice account settings
  3. Call your Google Voice phone number and conference in your voicemail number—it is important that Google Voice "sees" the call as an incoming call in order to record it. For example if you setup your Google Voice to forward calls to your cell phone, it will see it as an incoming call. In this scenario you can pick up the call on your cell, then conference in your voicemail and begin retrieving your messages
  4. Access your own voicemail by following the prompts and dialing the keypad as instructed
  5. Begin listening to your messages
  6. Record the voicemail message by following the PC calling program prompts (e.g. Google Voice hit 4 to start recording and 4 again to stop recording)
  7. Once your voicemail is completed, Google Voice will save the voicemail to your inbox where you can download it in Mp3 format. You can also save files by clicking the "Ctrl" and "S" keys at the same time to open a "Save" dialog box, choose a file name, then click the "Save" button to store the file on your hard drive
