Hi there, @hmorela! The best first step for optimizing two way audio is by checking for interference. Your device health RSSI reading will let you know if your Indoor Camera is receiving adequate signal. I recommend also checking the area around your Indoor Cam for any electronics or major appliances that might be interfering.
Please also ensure there is not a vpn enabled on your mobile device. If this concern persists, please give our support team a call at one of the numbers available here. You can also get in touch with our support team on Facebook @Ring.
