Phone call in/out callback

Declaration​

thread.register_event("xxtouch.call_callback", function(val)
    if (val == "in") then
        -- incoming call
    elseif (val == "out") then
        -- outgoing call
    elseif (val == "disconnected") then
        -- call disconnected
    end
end)

States​

  • in
    When an incoming call arrives, the process queue dictionary identified by xxtouch.call_callback receives this value.
  • out
    When a call is dialed out, the process queue dictionary identified by xxtouch.call_callback receives this value.
  • disconnected
    When an incoming or outgoing call ends, the process queue dictionary identified by xxtouch.call_callback receives this value.

Notes​

When the system receives phone call in/out messages, a state is pushed into the process queue dictionary identified by this message.

Example​

-- Clear message queue
proc_queue_clear("xxtouch.call_callback")
--
sys.toast("The script will now listen for call events and stop after 20 seconds")
--
-- Start listening
local eid = thread.register_event("xxtouch.call_callback", function(val)
    if (val == "in") then
        sys.toast("Incoming call")
    elseif (val == "out") then
        sys.toast("Outgoing call")
    elseif (val == "disconnected") then
        sys.toast("Call disconnected")
    end
end)
--
sys.msleep(20000) -- wait 20 seconds
--
-- Unregister callback; without unregistering, the script will not end here
thread.unregister_event("xxtouch.call_callback", eid)
