Hello..........!!!!

" We have seen those who teach foreign to the Muslim youth (for example) instead of saying As Salam alaykum , what does he say ? " Good Bye". We ask Allah , As Salamaah ( That He free us from this affliction)... Also on the public phones , when answering , what do people say ? " Hello". LA ILAAHA ILLALLAH  ( used in atonishment). Where is the statement os As Salam alaykum , which is from the sunnah?! So, when you answer the phone , say As salam alaykum , it is much better that the statement hello.
