why do my incoming calls get cancelled automatically?

Hey, I noticed that whenever a friend of mine calls, my phone just automatically cancels the incoming call. It is only his calls that get cancelled, I can answer all other incoming calls. What can I do about it?
I have a Samsung galaxy S duos7562.

I guess your surley have checked that the friend's number isn't in the "auto-reject list.
