    <div class="moz-cite-prefix">Thanks, George Joseph!<br>
      <br>
      Now a lot clearer the reasons for this behavior.<br>
      It turns out that in the case of devices there are two ways to
      understand that they are "alive":<br>
      1. Registration from device to server<br>
      2. qualify from the server to the client<br>
      And the second way does not seems superfluous. Since calling to
      the device this way will be used. if qualify doesn't working, then
      this call will not take place.<br>
      <br>
      Most likely the problem is that the device is behind two NAT (from
      your ISP and your own router).<br>
      Can you advise how to configure the client in this case? Is it
      necessary to use a stun (did not seem to help, and it only works
      in the case of RTP) or proxy?<br>
      <br>
      Thanks.<br>

              Is suspect two things:<br>
              1. delete a contact after the contact is added. But, like,
