What is the backdoor voicemail number for AT&T wireless?

I would like to leave someone a voice message but I do not know what they're service is. What is my backdoor voicemail number. Without having to talk to a random person.

1. Press the voicemail button on your phone, but it might not work if the other person doesn't have AT&T.
2. generally finding a backdoor is hard because different backdoor numbers work with different phone numbers. you can use a service like sendabuz - 888-5sendabuz - though to leave a voicemail for someone without their phone ringing.
