Want and call are both transitive verbs.

Your profile says that you are learning French. In French some past tense verbs become different if they are intransitive. I think that that is wrong because some verbs like "dormir" to sleep are treated as transitive even though they do not have a direct object ("I sleep on the bed" has a prepositional phrase but no object). I think you should memorize the list of verbs that take être instead of which verbs are transitive because that is not very important in French in my opinion
