Subject: an array of hashes

Hello all!
Can this be done better/nicer?
In @person i have an array of telephones. telephone is a hash with an id 
and a number, and i would like to join them.

@person.telephones.collect {|x| [] << x.number}.join(', ')

I don't know why, but I don't like this line of code... how would you 
write it?
