The ruling on answering the phone and clearing one's throat during prayer

Question:
Honorable Shaykh, may Allah grant you success. During the prayer, I answer the phone and clear my throat, or during the prayer I answer the phone, clear my throat, and hang up to indicate that the person in the house is praying, so that the caller can call back at another time. What is the ruling? And

Answer:
without speaking, if hanging up the phone is done without speaking, or clearing one's throat, if you are praying, this is permitted, yes, clearing one's throat is permitted to alert the one seeking permission to enter, but if there is speech, meaning you answered me in speech while you are praying, the prayer is prolonged by this, yes.
