Hello Everyone, 

I used yeastar Api to receive all calls in odoo without using odoo VOIP, yeaster Api.

using JS code i trying to make refresh access token every 1800 seconds and refresh every 60 seconds, i used setInterval function by this simple idea to refresh Access Token:

var refresh_access_token = setInterval(function(){ ajax.rpc('get_access_token').then(
function(data){  // data returned from python function.. 
    access_token = data.access_token;  // access token returned  from py function 
    interval_time = data.interval_time; // remaining time to refresh access token
}); } , interval_time);

but this idea not work because interval time must be static i think !.  

and for Web Socket i used:

const socket = new WebSocket('wss://some.some.com/openapi/v1.0/subscribe?access_token=' + access_token );

var te=setInterval(function(){
    socket.addEventListener('open', (event) => {
    socket.send('{"topic_list":[30011,30012]}');
    });

    console.log("hello from inteval")
},50000);

So gays i need good idea to refresh access token every 1800 seconds, and make wws stable.

Thanks all,
