Using a telephone is the most effective response when your transmission takes longer than 30 seconds. In communication protocols, especially in security and emergency responses, time is often critical. When a transmission is prolonged, it can indicate that the message is complex or that the current communication method is inadequate. Switching to a telephone allows for voice communication, which can convey details more efficiently, and also reduces potential disruptions on radio channels which might be urgently needed by others.

Furthermore, using a telephone ensures clarity and allows for immediate feedback, which is essential for timely decisions. In a situation where every second counts, quick, reliable communication can facilitate a more effective response and ensure that key details are not lost in translation.
