It took 20-30 seconds where the phone was frozen, but when it came back my visual voicemail buttons were active again and I could easily record my message. Nov 24, 2015 9:27 AM User profile for user: artursapek artursapek Jan 26, 2016 8:39 AM in response to phord In response to phord
So far you probably had a generic voicemail greeting on your iPhone and want to change it to a personal voicemail greeting and with most carriers you don’t even need an additional voicemail recording app and can record a custom voicemail greeting directly on iPhone.

Android phones can access voicemail by holding down the 1 key on the dial pad until the phone dials your 10-digit phone number. You will automatically connect to your mailbox and be prompted to enter your temporary password; this password is the last 4 digits of your phone number followed by the # key. Start the Google Voice app. Tap the three horizontal lines at the top left of the screen (sometimes called a hamburger menu), and then tap “Settings.” In the Voicemail section, tap “Voicemail greeting.” Tap “Record a greeting.” How do I access my voicemail? To call your voicemail on an Android phone, simply open your phone’s dial pad and hold your finger down on the “1” key. You can also call your voicemail from a different phone by calling your own number and tapping the pound key. How do you check your voicemail?
If you are using a IP 400 series desk phone, press the Voicemail function key. If you are using a Cisco 7900 series desk phone, press the "Messages" button (envelope icon). If you are calling from a phone other than your own desk phone, dial your own phone number and press the * key when you hear the voicemail greeting.
