"Mr.Tanner is telephoning a American Red Cross for help." vs "Mr.Tanner is telephoning an American Red Cross for help."

Both phrases are correct, but the second one is more commonly used. The choice between 'a' and 'an' depends on the following sound, not just the following letter. In this case, 'an' is used before 'American' because it starts with a vowel sound.
