It would matter because you could use an app like "Voice mail Forwarder"

Try this:
Step 1: Install Audacity, a free audio recording and editing program, on your Mac or PC. Launch it, then head to Edit > Preferences > Recording. And check the box next to "Software Playthrough."
Step 2: Plug your phone in to your computer's microphone jack using an auxiliary (aka stereo, aka mini to mini) cable. If you have an iPhone, hit "Record" on Audacity, then Play on your phone. When it's done playing back, hit stop.
If you have an Android or other phone that requires you to call your voice mail service, hit Record, then call your voice mail service and enter your PIN and play the message back as you would normally. When it's done, stop recording.
Step 3: If you need to, trim any extra audio before and after the actual voice mail by highlighting with your cursor and hitting Delete or Backspace on your keyboard.
Finally, go to File > Export and save the audio file in your preferred file type (like WAV or MP3). Now your voice mail is safely stored and you can pass it along to friends and family.
