audiocontext - Twilio.Device.setup throws error -


i developing browserphone twilio.js, version 1.4.20.

when token expired, handling twilio.device.offline(), , regenerate token , re-setup twilio.device.

after 6 times re-setup, then, twilio.js throw error.

*failed* construct 'audiocontext': number of hardware contexts provided (6) greater or equal maximum bound (6).

how can prevent error?

i'm using these code.

twilio.device.offline((device) => { if (navigator.online) {     twilio.device.destroy();     twilio.device.instance = null;     gettoken(device._clientname); }  const gettoken = (identity) => { $.ajax({     type: 'post',     url: baseurl + '/token/get',     data: {'identity': identity} }) .done((data) => {     data = json.parse(data);     twilio.device.setup(data.token, {         closeprotection: true     }); };
