Receiving a voice call

To receive a voice call, your application must monitor the phone control object (/pps/services/phone/private/control). When the phone service receives an incoming voice call, it writes the following information to that PPS object:

msg::incoming_call
dat:json:{"call_id":13}

To answer the call, you must send the answer_call command to the same object:

echo 'msg::answer_call\nid::1\ndat:json:{"answer_call_id":"13"}\n'
> /pps/services/phone/private/control

If the command is successful, the response is:

res::answer_call
id::1
dat:json:{"call_id":13}

To end the call, you must send the end_call command, specifying the call_id given in the response to the answer_call command:

# echo 'msg::end_call\nid::2\ndat:json:{"call_id":"13"}\n'
> /pps/services/phone/private/control

The response is:

res::end_call
id::2
dat:json:{"call_id":13}

The logging information shows the following activity:
