Adhan on Phone & Adhan of Masjid
Adhan is the announcement of the beginning of a one of the five obligatory prayers, during the day or night.
The Rulings of the Adhan and the Iqamah
The adhan and the iqamah are fardh kifiyah (a collective responsibility) for the Muslim community, but only for the five compulsory prayers.
Malik bin Huwairith narrated, I came to the Prophet (peace be upon him) with some men from my tribe and stayed with him for twenty nights. He was kind and merciful to us. When he realized our longing for our families, he said to us, “Go back and stay with your families and teach them the religion, and offer the prayer and one of you should pronounce the Adhan for the prayer when its time is due and the oldest one amongst you should lead the prayer.” (Al-Bukhari)
A general rule is to follow the adhan you hear from your mosque. That should be the adhan you follow, repeat and make du`aa’ (supplication) after. The adhan on phones cannot be treated similarly to the adhan from a masjid.
