    <p>Hello,</p>
    <p>do not reply to mailing list digest messages, they have no
      relation to the message you want to continue the discussion.</p>
    <p>If you want to engage in an active discussion, disable the digest
      option and follow up by replying to specific messages.<br>
    </p>
    <p>Or just create a new message, and if you want to refer to an
      existing discussion, then paste the link to the thread discussion
      on mailing list web archive.</p>

          <br>
          After a while, I finally got the connection from my Kamailio
          server to MsTeams and I can validate that the connection to
          MsTeams is in AP.<br>
          <br>
          [root @ kamailio-server kamailio] # kamcmd dispatcher.list |

          transport = tls<br>
                                                  FLAGS: AP<br>
          <br>
          However, from the admin panel of MsTeams (Direct Routing) I
          see that the connection to my sbc "<a
            href="http://sbc.netvoiceperu.com" moz-do-not-send="true">sbc.netvoiceperu.com</a>"
          is with TLS connectivity status in "Active" but the SIP
          options status is in "Warning".<br>
          <br>
          I have made calls from MsTeams thinking that the SIP options
          status would change to "active" but it is still in "Warning"
          state. On the other hand, I have enabled a siptrace in
          Kamailio and verify that the SIP OPTIONS from kamailio are
          being sent in the following format to MsTeams.<br>

          However I don't see the 200 OK SIP responses from Kamailio to

          <br>
          I think this may be the reason why I see the SIP OPTIONS
          status in "Warning" from the MsTeams panel. Maybe the contact
          field is not being added in the SIP OPTIONS messages that
          Kamailio sends to MsTeams and for that reason I don't see
          200OK responses from MsTeams.<br>
          <br>
          Could you help me solve this please.<br>

          I am a friend of Willy and we are doing this integration,
          today I create wildcard certificates in letsencrypt, for this
          use acme.sh and integrate it with the DNS CLOUDNS provider,
          the certificates were generated successfully, we replace the
          old ones, in the LOGs it gives us understanding q accept the
          certificates.<br>

          Does this happen when Kamailio connects to MS Teams? The logs

          <br>
          You can set debug=3 in kamailio.cfg and see if the DEBUG

          Letsencrypt certs in Kamailio and accepting what ever MS sent
