    4. Click Save.
    5. Repeat Step 5.a. through Step 5.d. for each domain.
    Step 5   Make sure that the domain has an associated DNS record that resolves to the Cisco Expressway-E. The domain information is propagated from the Cisco Expressway-C to the Cisco Expressway-E through the SSH tunnel (port 2222). It is used by the Cisco Expressway-E to validate incoming HTTP requests for the Cisco Jabber Guest service.
    Step 6   On the Cisco Expressway-C, associate the Cisco Jabber Guest servers with the domain: This allows the Cisco Expressway-C to route HTTP requests with this domain to the appropriate Cisco Jabber Guest server.
    1. Choose Configuration > Unified Communications > Configuration.
    2. In the Advanced section, click Configure Jabber Guest servers.
    3. Click New.
    4. For Server hostname, enter the FQDN of the Cisco Jabber Guest server.
    5. For Priority, enter the priority of the Cisco Jabber Guest server. Lower numbers have higher priority.

      Make sure that all Cisco Jabber Guest servers have a different priority so that calls are only sent to one Cisco Jabber Guest server in the deployment at a time.

    6. From the Domain drop-down list, select the Cisco Jabber Guest HTTP domain.
    7. Click Create entry.
    8. Repeat Step 6.c. through Step 6.g. for each Cisco Jabber Guest server in the cluster.

    10. In the Location section, for Peer 1 address, enter the IP address or FQDN of the Cisco Jabber Guest server.
    11. In the Advanced section, from the Zone profile drop-down list, select Default.
    12. Click Create zone.
    13. Repeat Step 7.b. through 7.l. for each Cisco Jabber Guest server in a Cisco Jabber Guest cluster. Do not configure any search rules for these neighbor zones. These zones are used to receive traffic only.
    Step 9   Set up a connection between the Cisco Expressway-C and Cisco Unified Communications Manager:
    1. On Cisco Unified Communications Manager, set up a non-secure or secure SIP trunk and point it to the Cisco Expressway-C.
    2. On Cisco Expressway-C, set up a neighbor zone and point it to Cisco Unified Communications Manager.

    Follow the steps in the Cisco Unified Communications Manager with Cisco Expressway (SIP Trunk) Deployment Guide.

    Step 10   Create a search rule on Cisco Expressway-C to route calls to Cisco Unified Communications Manager.
    Step 11   Force the protocol between the Cisco Jabber Guest server and the Cisco Expressway-C to be http:
    1. Sign in to the Cisco Expressway-C command-line interface as an administrator. In a clustered Cisco Expressway-C deployment, sign in to the master Cisco Expressway-C.
    2. Enter the following command: 
      xconf CollaborationEdge JabbercProxyProtocol: http

    HTTP request goes from the Cisco Expressway-E to the Cisco Expressway-C to the Cisco Jabber Guest server.

      Change MTU Size

      In some call scenarios, such as when using VPN, the default Maximum Transmission Unit (MTU) on Cisco Expressway-E is too high and can cause packet loss. The default MTU is 1500 bytes. We recommend that you lower the MTU to 1400 bytes. If you do not, callers may experience problems, such as one-way video.

      Procedure
        Step 1   On Cisco Expressway-E, do one of the following:
        • If you have Cisco Expressway-E X8.2, choose System > IP.
        • If you have Cisco Expressway-E X8.5 or later, choose System > Network Interfaces > IP.
        Step 2   In the LAN 1 section, for Maximum transmission unit (MTU), enter 1400.
        Step 3   Click Save.

        Configure Signaling and Media

        Do one of the following:

        BFCP Screen Share

        Existing Cisco Expressway and Cisco Unified Communications Manager deployments that use Binary Floor Control Protocol (BFCP) should not need any configuration changes to enable Cisco Jabber Guest for BFCP screen share. If you're not sure if your deployment has BFCP enabled, see Check BFCP Settings for Screen Sharing.

        Related Tasks
        Check BFCP Settings for Screen Sharing

        Configure Signaling and Media: Cisco Expressway-E with Single NIC Deployment

        We recommend enabling Session Initiation Protocol (SIP) over Transport Layer Security (TLS) for call control signaling and enabling Secure Real-Time Transfer Protocol (SRTP) for secure media. Secure media requires secure signaling.

        Before You Begin

        On Cisco Expressway-C, make sure that you have created a neighbor zone for each Cisco Jabber Guest server. For more information, see Configure Cisco Expressway-E and Cisco Expressway-C: Cisco Expressway-E with Single NIC Deployment.

        Procedure
          Step 1   To enable SIP over TLS, obtain the Cisco Expressway-C server certificate or the Cisco Expressway-C certificate authority certificate:
          • If you have a single Cisco Expressway-C, obtain the Cisco Expressway-C server certificate.
          • If Cisco Expressway-C is a cluster of servers, obtain the Cisco Expressway-C certificate authority certificate. This certificate must be uploaded to the Cisco Jabber Guest server so that Cisco Jabber Guest can communicate with all nodes in the Cisco Expressway-C cluster.
          Step 2   Upload the certificate to Cisco Jabber Guest Administration:
          1. Sign in to Cisco Jabber Guest Administration as an administrator.
          2. Click Settings, and then click Secure SIP Trust Certificate.
          3. Under Secure SIP Trust Certificate, click Choose File.

          5. For SIP port, enter 5061.
          6. For SIP domain, enter the SIP domain. This setting is used if the Cisco Jabber Guest link does not contain a SIP domain. In most cases, this is the enterprise SIP domain as configured in Cisco Unified Communications Manager.
          7. For SIP server, enter the IP address or FQDN of the Cisco Expressway-C.
          8. Specify whether SIP is sent to the Cisco Expressway-C that originated the HTTP call control or to the server entered above.
          Step 4   Click Update. The message Update successful appears.
          Step 5   Restart Tomcat: 
          service tomcat-as-standalone.sh restart
          Step 6   On the Cisco Expressway-C, verify that the neighbor zones for each Cisco Jabber Guest server are active:
          1. Choose Configuration > Zones > Zones.
          2. View the SIP status column.

          Configure Signaling and Media: Cisco Expressway-E with Dual NIC Deployment

          We recommend enabling Session Initiation Protocol (SIP) over Transport Layer Security (TLS) for call control signaling and enabling Secure Real-Time Transfer Protocol (SRTP) for secure media. Secure media requires secure signaling.

          Before You Begin

          On Cisco Expressway-E, make sure that you have created a neighbor zone for each Cisco Jabber Guest server. For more information, see Configure Cisco Expressway-E and Cisco Expressway-C: Cisco Expressway-E with Dual NIC Deployment.

          Procedure
            Step 1   To enable SIP over TLS, obtain the Cisco Expressway-E server certificate or the Cisco Expressway-E certificate authority certificate:
            • If you have a single Cisco Expressway-E, obtain the Cisco Expressway-E server certificate.
            • If Cisco Expressway-E is a cluster of servers, obtain the Cisco Expressway-E certificate authority certificate. This certificate must be uploaded to the Cisco Jabber Guest server so that Cisco Jabber Guest can communicate with all nodes in the Cisco Expressway-E cluster.
            Step 2   Upload the certificate to Cisco Jabber Guest Administration:
            1. Sign in to Cisco Jabber Guest Administration as an administrator.
            2. Click Settings, and then click Secure SIP Trust Certificate.
            3. Under Secure SIP Trust Certificate, click Choose File.
            4. Select the certificate that you obtained, and then click Upload.

            5. For SIP port, enter 5061.
            6. For SIP domain, enter the SIP domain. This setting is used if the Cisco Jabber Guest link does not contain a SIP domain. In most cases, this is the enterprise SIP domain as configured in Cisco Unified Communications Manager.
              Important:

              For proper call routing, the SIP domain must be configured on the Cisco Expressway-E search rule to point to the traversal zone.

            7. For a single Cisco Expressway-E server, for SIP server, enter the IP address or FQDN of Cisco Expressway-E's internal NIC.
            8. Select where to send SIP traffic:

              • For a single Cisco Expressway-E server, select SIP server specified above.

              • For cluster of Cisco Expressway-E servers:

                1. Select Expressway-E server that provided TURN service.

                  Important:

                  The TURN relay and SIP signaling must reside on the same server.

                2. Under Cisco Expressway-E Network Address Map, enter the external IP addresses and internal IP addresses of each of the Cisco Expressway-E servers in the cluster. Mapping allows the Cisco Jabber Guest server to send the SIP to the same Cisco Expressway-E servers as the TURN relay.

                  If static NAT mode is enabled on Cisco Expressway-E with either single NIC deployment or dual NIC deployment, the Cisco Jabber Guest server must be configured for static NAT mode as well.

            Step 4   Click Update. The message Update successful appears.
            Step 5   Restart Tomcat: 
            service tomcat-as-standalone.sh restart
            Step 6   On the Cisco Expressway-E, verify that the neighbor zones for each Cisco Jabber Guest server are active:
            1. Choose Configuration > Zones > Zones.
            2. View the SIP status column.

            Configure Static NAT Mode on Cisco Expressway-E

            If static NAT mode is enabled on Cisco Expressway-E with either single NIC deployment or dual NIC deployment, the Cisco Jabber Guest server must be configured for static NAT mode as well. This allows the media to flow within the DMZ, avoiding NAT reflection (sending media to the NATed address).
            Procedure
              Step 1   Sign in to Cisco Jabber Guest Administration.
              Step 2   Click Settings, and then click Call Control and Media.
              Step 3   Under Cisco Expressway-E Network Address Map, check Static NAT mode. This check box appears only when the option,Route calls using Cisco Expressway, is selected.
              Step 4   Under Public IP (Static NAT), enter the static NAT IP address of the Cisco Expressway-E server.
              Step 5   Under External IP (DMZ), enter the external IP address of the Cisco Expressway-E server.
              Step 6   Repeat Steps 4 and 5 for each of the Cisco Expressway-E servers in the cluster.
              Step 7   Click Update.

              Configure TURN Credential Provisioning

              The Cisco Jabber Guest client needs TURN credentials to allocate TURN relays on the Cisco Expressway-E. The Cisco Jabber Guest server provisions these credentials on the Cisco Expressway-C when the Cisco Jabber Guest client connects.

              The Cisco Jabber Guest server uses an HTTP-based XML API to communicate with Cisco Expressway-C.

              Procedure
                Step 1   Sign in to Cisco Jabber Guest Administration as an administrator.
                Step 2   Click Settings, and then click Call Control and Media.
                Step 3   Under Cisco Expressway-C, for Expressway-C (IP address or DNS name), enter the Cisco Expressway-C IP address or DNS name.
                Step 4   Specify whether short-term TURN credentials are requested from the Cisco Expressway-C that proxied the HTTP request from the Cisco Jabber Guest client or from the server entered in Step 3.
                Step 5   For HTTPS port, specify the port.
                Step 6   For Domain, enter the domain on Cisco Expressway-C that has Jabber Guest services enabled.
                Step 7   For Username and Password, enter the username and password of the administrator account on Cisco Expressway-C that has read, write, and API access.
                Step 8   Click Update.

                Set Up TURN Server Information

                The Cisco Jabber Guest client needs to know which Cisco Expressway-E to use for TURN relays.

                Procedure
                  Step 1   Sign in to Cisco Jabber Guest Administration as an administrator.
                  Step 2   Click Settings, and then click Call Control and Media.
                  Step 3   Under Cisco Expressway-E, for Expressway-E TURN server (IP address or DNS name), enter the Cisco Expressway-E TURN server outside IP address or DNS name.

                  If you have a cluster of Cisco Expressway-E servers, see Configure Round-Robin DNS Load Balancing or Configure Round-Robin CSV Loading Balancing.

                  Step 4   For TURN port, enter the UDP port. The port is typically 3478 but you can enter a range of ports, such as 3478-3483. The range is necessary if the Cisco Expressway-E supports multiple TURN ports.
                  Important:

                  The port must match the port specified on the Cisco Expressway-E (under Configuration > Traversal > TURN).

                  Step 5   Click Update.

                  Set FQDN of Cisco Jabber Guest Server

                  Procedure
                    Step 1   Sign in to Cisco Jabber Guest Administration as an administrator.
                    Step 2   Click Settings, and then click Call Control and Media (Local).
                    Step 3   Enter the FQDN of the Cisco Jabber Guest server.
                    Important:

                    The FQDN must match the value specified in the Cisco Jabber Guest Server hostname field on the Cisco Expressway-C. Cisco Expressway-C uses the FQDN to forward the per-session HTTP traffic to the appropriate Cisco Jabber Guest server in the cluster.

                    Step 4   Click Update.
                    What to Do Next

                    Make sure that you populate the Cisco Jabber Guest local FQDN field for each node in the Cisco Jabber Guest cluster.

                    Set Domain Used for Links

                    To create links on the Cisco Jabber Guest server, you must enter the Cisco Jabber Guest domain that is configured on the Cisco Expressway-C or the sub-domain of the Cisco Jabber Guest domain.

                    You also need to ensure that the appropriate DNS records exist so that the Cisco Jabber Guest client can reach the Cisco Expressway-E.

                    Procedure
                      Step 1   Sign in to Cisco Jabber Guest Administration as an administrator.
                      Step 2   Click Settings, and then click Links.
                      Step 3   For Domain used for links, enter the Cisco Jabber Guest domain that is configured on the Cisco Expressway-C. You can add a sub-domain for the Cisco Jabber Guest service. Make sure that the domain used for links has an associated DNS record that resolves to the public IP address of Cisco Expressway-E.

                      Example:If yourcompany.com is configured as the Cisco Jabber Guest domain on Cisco Expressway-C and jg.yourcompany.com is configured on the Cisco Jabber Guest server, the format of the link is https://jg.yourcompany.com/call/<directory number>. And make sure there is a DNS record to resolve jg.yourcompany.com to the public IP address of Cisco Expressway-E.
                      Step 4   Port Remapping: If there is no port remapping in front of Cisco Expressway-E, then you can add port 9443 after the domain.

                      Example:jg.yourcompany.com:9443 is configured on the Cisco Jabber Guest server, the format of the link is https://jg.yourcompany.com:9443/call/<directory number>.

                        Customize Cisco Jabber Guest Clients

                        Important:

                        Do not to modify any files on the Cisco Jabber Guest server. For example, on the web client, editing the appearance of the Cisco Jabber Guest video window, such as the Call button, is not supported.

                        To change the appearance of the web page that contains the Cisco Jabber Guest video window, host the page on a server other than the Cisco Jabber Guest server.

                        The mobile client can be fully customized.

                        For more information about customizing Cisco Jabber Guest clients, go to the Cisco Jabber Guest SDK DevNet website.
