Voicemail Greeting

I have a problem. . .

I have a professionally produced voicemail greeting, and unfortunately I do not have a copy due to a computer malfunction!

Currently I am having a issue with Sprint which is now 7 days. . . My phone does not ring, but the caller is capable of leaving a voicemail message.

I would like to change my custom professionally produced greeting with one letting my clients know that my phone is not working correctly and does not ring. But I don't want to lose my paid for message and yes I could hold the phone to my computer and record the message but I have done that before and it seems the quality degrades.

Why doesn't Apple have more that one option to save custom recorded greetings. OR how can I save my greeting in some other way so I can retreive it why Sprint gets there act together.
