Riddle Corner

It's been quite a long time we don't have new topic for conversation.
This time it's riddle game.
I will provide 1 riddle and anyone who can answer it will provide another 1 riddle, and so on. Let me start.

I can be quick and then I'm deadly,
I am a rock, shell and bone medley.
I was made into a man, I'd make people dream.
What am I?

a sand?

Yeah! Answered on the first reply..
It will be harder next time! I promise! :twisted evil: mwahahahahahaha

Your turn..

No new riddle?
Then I will make one.

A man has come home from work to find that his no-good flatmate has left a message by the telephone. It reads :
8447 835374663 47 653 263 3637 668 9675 438 2 639 663

Crack the code!

he left message in the telephone? So i guess each number represents one of three alphabet we can find in the display number of the telephone.
so i think this is the code:

"this telephone is old and does not work get a new one"

oh and i forgot that i owe a riddle..
so here it is:

"A man wanted to enter an exclusive club but did not know the password that was required. He waited by the door and listened. A club member knocked on the door and the doorman said, "twelve." The member replied, "six " and was let in. A second member came to the door and the doorman said, "six." The member replied, "three" and was let in. The man thought he had heard enough and walked up to the door. The doorman said ,"ten" and the man replied, "five." But he was not let in."

Question: What should have he said and why?

three
