eCall (Emergency Call System) is a European-mandated safety feature that automatically contacts emergency services (112) in the event of a serious accident.
Transfers a Minimum Set of Data (MSD) — including vehicle location, time, direction, and crash data — to the nearest Public Safety Answering Point (PSAP).
Supports manual SOS calls (MEC) and automatic crash notifications (ACN).
Reduces response time by up to 50% in rural areas and 40% in cities, saving lives every day
Uses 2G/3G networks to transmit the MSD over the voice channel via an in-band modem — the mandatory system across the EU since 2018

Private SOS
Operates over 4G (LTE) / 5G (NR) networks, sending the MSD through SIP INVITE and SMS to a Trusted Service Provider (TSP) such as Bosch
