Abu-Rafi, a companion of the Prophet reports: "I saw the Prophet (peace be upon him) calling the 'athan' close to the ear of Al-Hassan ibn Ali (the Prophet's grandson) when his mother Fatimah (the Prophet's daughter) gave birth to him." (Related by Abu Dawood, Ahmad, At-Tirmithi and others). You see there is a Hadith which is related by quite a few of the best known scholars. There is another Hadith reported by Ibn Abbas which gives further support to this one. This means that the practice is recommended. If someone does not do it, he misses reward from Allah for not practicing what is recommended. However, he violates no principle of Islam.
