Making an eCall

You can make an eCall (i.e., a Cellular Emergency Call for Vehicle) by sending the start_ecall command (which defines many required parameters such as ecall_type, vehicle, and vin) to the phone control object:

# echo 'msg::start_ecall\nid::1\ndat:json:{"ecall_type":"test",
    "confidence":true,"vehicle":1,"vin":"1M8GDM9AXKP042789",
    "storage_type":2,"time_stamp":1326752314,"latitude":164565698,
    "longitude":49457972,"direction":157,"delta_latitude":0,
    "delta_longitude":0,"passengers":31}\n'
> /pps/services/phone/private/control

The response is:

res::start_call
id::1
dat:json:{"call_id":2}

To end the call, you must send the end_call command to the same PPS object, specifying the call_id given in the response to the start_ecall command:

# echo 'msg::end_call\nid::2\ndat:json:{"call_id":"7"}\n'
> /pps/services/phone/private/control

The response is:

res::end_call
id::2
dat:json:{"call_id":7}

The logging information shows the following activity:

• Starting of the eCall
• Network confirmation that the emergency number is ringing
• Application receives a response to the start_ecall command, where the call_id is included
• Audio is started
• Emergency voice call is connected
• Minimum Set of Data (MSD) buffer is uploaded
• Public Safety Answering Point (PSAP) operator disconnects the call
• Audio is stopped
