Possible causes of Null Session sometimes.

Hi Conrad, The browser phone is working great so far. Today I saw Audio Answer failed, null session message in the console for the first time. I'm sharing the log :

Wed Oct 28 2020 10:39:58 GMT+0530 (India Standard Time) | sip.sipmessage | header "Content-Disposition" not present Wed Oct 28 2020 10:39:58 GMT+0530 (India Standard Time) | sip.dialog | new UAS dialog created with status EARLY New Incoming Call!

Audio Answer failed, null session AnswerAudioCall @ phoneV6.js:2722 web_hook_on_invite s web_hook_on_invite @ phone.html:91 Audio Is Playing ... Registered! web_hook_on_register r

Today I got a message Audio Answer failed, null session from the AnswerAudioCalls function. I need your help to understand in which case the getSession() function can return the session as null.

Thank you

This could happen if:

    var session = getSession(buddy);

returns null, and it would rerun null if this code does not find the session

    var rtnSession = null;
    $.each(userAgent.sessions, function (i, session) {
        if(session.data.buddyId == buddy) {
            rtnSession = session;
            return false;
        }
    });
    return rtnSession;

It is possible that the session is removed from the array in userAgent.sessions array, before this code executes. It may have been an unusual race condition. If you can try trace the sequence of events it may help.
