Once you've received a voicemail in Google Voice, you have access to it, and storage in the archives as well. However, since I've pretty much brought everything together in Evernote, I wanted to have important voicemails stored there as well. The search ability in Evernote is great, and the voicemails from Google Voice contain the name of the caller, their number, a transcription to text, and a link to the voicemail.
At the bottom of every voicemail is the "more" link, which gives you several options, including "Add Note" and "Email." It couldn't get any better. If I want to add a quick note clarifying the context of the call, I can. Then, with the email address provided by Evernote, I just send it to my Evernote account. Since the email box uses Google Contacts, I just put in a contact "Evernote" and it pulls the email address right up when I start typing "Evern..."
As you can also record conversations with Google Voice by simply hitting the "4" key during an outgoing call, you can do the same thing with a recorded conversation. GVoice announces the call is being recorded, so you're not hiding it. What you might use it for is a conversation where directions or detailed instructions are being discussed, and you want to recall them verbatim. Once it's recorded, the same "more" link lets you add a note and email it to Evernote. For real estate professionals, this could be instructions from a client on something they want added to a contract, as an example.
