Custom VM Greeting

Well no. You can always call in to voicemail and record a new greeting. The visual voicemail app allows you to change greetings at least on the Android version. When I had an iPhone I could record a greeting by calling voicemail and going through the menu for voicemail greeting. Digits had no effect on that. But to be clear I never got digits to work correctly with my iPhone.

but like I said previously if you'll call in to your voicemail select your voicemail greeting and record a new greeting you can record whatever is playing in the background from another speaker and that can be your new greeting.
