javascript - When making a call from the browser, how can I tell programmatically when the call has been answered? -

i'm writing web client flask, , integrating twilio allow me create phone calls browser. , good, it's working, have status info want update when phone call answered.

the connection.status() method doesn't seem help, since "open" seems mean phone call attempting go through, , status stays open until "closed" when phone call ends.

is there way (either through browser or registering callback python code on server) status update when phone call transitions "ringing" "live" ?

for outbound calls

the twilio.js library states:

twilio.device main entry point creating outbound connections, accepting incoming connections, , setting connection event handlers.

within device documentation, goes on state .status() method:

returns status of device.

the key here in code snippet:

twilio.device.incoming(function(conn) { console.log(conn.parameters.from); conn.status // => "pending" conn.accept(); conn.status // => "connecting" });

now key here remember device.incoming used when outbound phone call has been made browser specified here:

the device.incoming handler function called when incoming event fired. triggered whenever incoming connection outbound rest phone call or twiml <dial> device made.

with above code snippet, able check

conn.status

to "connecting" when connection transitioning open status , "open" 1 time phone call picked outgoing call. result able set flag , log 1 time outbound phone call picked up. twiml used:

<response> <dial callerid="+1888xxxxxxx"> {{insert phone number here}} </dial> </response>

here documentation device specifications , general twilio.js library:

and
