The Android operating system includes a native visual voicemail that lets you view voicemail messages in text form. If you have an older Android phone or if your service provider doesn’t offer visual voicemail, you can download a third-party app. Select Phone. Select Keypad. Press and hold the number 1. If your voicemail is not set up, select ADD NUMBER. Select Voicemail number. Enter the Voicemail number and select OK. Repeat steps 2-4 to check your voicemail.
On the iPhone, go into voicemail and tap "Greeting". Record a few seconds of something and tap stop. Before you tap save, use iFuntastic or SFTP to navigate to /var/root/Library/Voicemail on your iPhone. You'll see a file called "Greeting. amr". This is the audio you just recorded. Delete that file and replace it with your custom message which should then be renamed to "Greeting.amr". Tap "Play" on the iPhone to verify your message works. If it plays, tap "Save" and your custom message will be uploaded to AT&T's servers.

Techjunkie.com One sign that your phone calls are being ignored is how many rings before it goes to voicemail. Generally, the feedback ringtone will go through several cycles before the voicemail message comes up. If upon placing the phone call, it rings only once or twice and goes to voicemail then your calls are probably being declined. 443 is also the number to dial to retrieve voicemails. To switch voicemail off dial 1626. Voicemail deducts one minute from your Goodybag regardless of length of call (assuming you have minutes left) or, if not, costs 8p per call.
