It’s almost inevitable that we’ll all need to securely and reliably save a voicemail at some point. Whether it’s a message from a loved one who has since died or just an important recording you want to keep, there are several ways to save important voicemails indefinitely.

Fake phone numbers are a beautiful thing, whether you make them up on the spot or give out the number to a service like the Rejection Hotline. Best of all, though, are the ones you craft yourself, like the one I gave to car dealers that fakes a full voicemail message.

Congratulations Google Voice loyalists. Your time has finally come. After years of languishing on the vine, Google has finally updated its phone service with a new look and some new features for its Android, iOS and web clients.

If you're on Telstra prepaid and you use voicemail, life is about to get a little more costly. If you're on the Cap Encore plan (the most heavily promoted of Telstra's prepaid offers), from July 31 retrieving voicemail will be charged from your recharge credit rather than your call credit.

Never manage to answer your phone before it diverts to voicemail? You can alter the length of time it rings by dialling a simple number.

It's become a mantra of tech-involved 20- and 30-somethings (and even teenagers) that you should only call when it's an emergency, otherwise texting is preferred. But what about voicemails? Should you ever leave one?

When Telstra announced it would offer visual voicemail on iPhones, we ran through an analysis of whether the service was worth paying for. Here's one specific scenario we didn't consider: retrieving voicemail when overseas.

Bad news if you don't fancy paying Telstra $5 a month for its newly-announced iPhone visual voicemail service and don't think Vodafone is up to the task: Optus says it has no plans for adding the option for its iPhone customers.

As we foreshadowed yesterday, Telstra is belatedly adding the visual voicemail feature for iPhone users -- but if you want it, you'll have to pay $5 a month for the privilege. Is that a worthwhile investment? The answer is "maybe", if you get a lot of voicemail from a fairly predictable group of contacts.

Telstra hasn't yet officially confirmed it online, but some Twitter users have reported that visual voicemail is now available as an option for their Telstra iPhone accounts -- for an additional $5 a month.

Voicemail is a tough cookie to crack. Some people love it, but as short text messages have overtaken quick communication on phones (SMS) and the internet (e.g. Twitter), voicemail has fallen out of favour with many.

Mobile phone plans are often sold on their total cap value and their general call rate, but the charges for texts, MMS messages and voicemail access can quickly mount up. Planhacker compares what's on offer from the major providers.

Ed. Note: If you've noticed how many people have voicemail messages that sound like they're gasping for air when they record them, this simple trick from reader Gregor Samosa will help you leave smooth radio-announcer-quality messages.

The good news? Optus is offering a voicemail-to-text conversion service. The bad news? It'll cost you $6.99 a month.

Web marketer and migraine sufferer Scott Clark is tracking all the daily variables—food, environment, activity, and the like—that surround his attacks with a migraine diary, and he's found text-to-speech services like Jott (original post) are the best hassle-free tool for the job. Not only will Jott (or ReQall or most similar systems) automatically record the date and time of the entries, but it's always accessible by cell phone, and one can create a dedicated "inbox" for migraines to separate the diary from productivity-related uses. For anyone looking to track a diet, health issue, or other things that happen away from the desk, it's worth looking into. Photo by robtxgal. Migraine Diary Creation using Jott

Mac OS X only: The latest beta 3 release of Yahoo Messenger for Mac adds voice and voicemail capabilities a la Skype. Using Yahoo Messenger, computer to computer voice calls are free, and you can purchase a PhoneOut and/or PhoneIn account to call land line or cell phones, or receive calls on your computer, or even set up call forwarding to land lines or mobile phones. (Rates start at 1 cent/minute in the U.S.) You can also send SMS messages with Yahoo Messenger, and get free voicemail; Yahoo Messenger delivers voicemail as an email attachment to the address you specify. Skype's had all these features for Mac and PC for some time now, so Yahoo's pretty late to the game—but it's still good to have options. Mac Version - Yahoo! Messenger
