In this scenario, an XMPP user juliet type2. Therefore the type2. Because the type2. Therefore it sends a dialback key to type1. The authoritative server for the type2. Here we assume that the authoritative server for the type2. Because the connection is successful, the type2.
Because the example. We assume that type2. Because the type3. Because type4. Notice that type4. Therefore type2. Because type5. Notice that type5. Because type6. The servers then attempt negotiate TLS. We assume the negotiation fails because type2.
Because the connection is unsuccessful, the type2. In this scenario, an XMPP user romeo type3. Therefore the type3. The authoritative server for the type3. Here we assume that the authoritative server for the type3. Because the connection is successful, the type3. We assume that example.
Therefore type3. Notice that type6. In this scenario, an XMPP user hamlet type4. Therefore the type4. Because the connection is unsuccessful, the type4. Notice that type2. Therefore type4.
Requirements for XMPP. End-to-end encryption is not available for third party federated users. You can only choose one XMPP domain. Choose your cluster from the following options, based on the location of your Webex data center: US cluster— wx2i-a. Was this article helpful? Two things are needed to achieve this:. For a large number of domains, this is potentially quite awkward to configure and maintain reliably, particularly TLS certificates with large numbers of SubjectAlternateNames.
A very simple trunked architecture is a star configuration. This is straightforward to set up with peering controls. A server which is a "point", is simply set up with a peering control that routes traffic to the centre node. The centre node might be a core national node connecting a number of separate national services.
The centre node will have a peering control to route traffic to the domains managed by each of the star points, and may also have peering controls to route to other domains, and in particular cross domain. In a boundary architecture, peering controls will be used to route to edge servers that control and check traffic flowing cross domain.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Users of a federated Lync Server deployment or XMPP deployment have access to a limited set of services and are authenticated by the external deployment.
Remote users are members of your Lync Server deployment and have access to all services offered by your deployment. For details, see Support for public instant messenger connectivity in Lync Server Public instant messaging connectivity is a special type of federation that allows a Lync Server client to access configured public Instant Messaging partners using the Lync The current public instant messaging connectivity partners are:.
A public instant messaging connectivity configuration allows Lync users access to public instant messaging connectivity users by:. A Lync Server federated configuration allows Lync users access to federated users by:. For any other XMPP systems contact the third-party vendor to verify that they support federation with Lync Server , and for any deployment or troubleshooting recommendations.
