        </div>
        <div>I am having trouble to send/receive OPTIONS to ms teams. </div>
        <div>Using the dispatcher module. The socket is defined as tls:<b>mysbcip</b>:5061</div>
        <div>Looks like when my opensips (3.2.x) tries to send OPTIONS.
          it is giving me the following error </div>

        <div>Looks like the client domain is used for outgoing TLS
