Can't make incoming calls as because the extension is UNREACHABLE.

I'm facing UNREACHABLE issue on ctxSip phone. Where actually I'll change in sip.js file please assist me. Thanks in Advance.

My sip.js version is: useragent "SIP.js/0.7.8"

My sip.js contact uri:

     while(contacts--) {
        contact = response.parseHeader('contact', contacts);
        if(contact.uri.user === this.ua.contact.uri.user) {
          expires = contact.getParam('expires');
          break;
        } else {
          contact = null;
        }
      }
