A. 1. Check Microphone and Speaker: Ensure that your iPhone's microphone and speaker are functioning properly by testing them with other apps (like Voice Memos or Phone calls). 2. Adjust Audio Settings: In the Securus app, check if there are any audio settings that can be adjusted for better quality.

B. 3. Use Headphones: Sometimes, using wired or Bluetooth headphones can improve audio quality during calls.
