Help Cant undo call rejection

[klau17]

Hi: I just got a galaxy s2 and i was trying my ringtone and I called from my house phone to my cel phone. By mistake I rejected the call. So, my future calls from my house phone are being rejected. I went to settings, call, call rejection and my house phone is NOT on the auto reject list and the auto reject mode is off. If I go to call logs the phone call still appears as rejected. I dont know what else to do since it is NOT on the auto reject list!

Any help would be appreciated!

Thanks!
