Enable Federation between Cisco Jabber and Microsoft Skype For Business (SFB) Server



Integration Scenarios

XMPP service runs on Skype For Business (SFB) Front End and Edge Server. You can use this component to federate with internal or external Jabber setup. You can also share same name space between the platforms. Thus, enabling instant messaging (chat) and presence between Jabber and SFB users.

This article helps you federate Cisco Unified Presence Server setup with Skype For Business Server\Pool.

Scenario

You want to federate your organization, Contoso.com, with another organization, Fabrikam.com. Contoso.com is running Skype For Business (SFB) server, and Fabrikam.com is running Cisco Jabber. This article helps you configure federation between the two domains.

DNS Requirement

You need to have following DNS entry in public DNS server.

Name Host Port Reason
_xmpp-server._tcp.contoso.com sip.contoso.com 5269 XMPP gateway locator

In this case, sip.contoso.com is the FQDN of the Access Edge server.

Name Host Port Reason
_xmpp-server._tcp.fabrikam.com sip.fabrikam.com.com 5269 XMPP gateway locator

Firewall Requirement

Allow bi-directional communication to TCP port 5269 to Edge Server XMPP proxy (Contoso.com) from federated XMPP partner (Fabrikam.com).

Allow TCP port 23456 from Skype For Business Front End Server to the Edge Server’s internal interface.

Following diagram explains the other firewall requirement of Skype For Business (SFB) Edge server.


Configure Skype For Business Server Settings

You need to have Skype For Business Servers (Front End & Edge) deployed. Refer to following articles if not already deployed.

Step by Step : Deploy Skype For Business (SFB) Front End Server

Step by Step : Deploy Skype For Business (SFB) Edge Server

Configure EXTERNAL ACCESS POLICY

Launch Skype For Business (SFB) Control Panel. In the left navigation bar, click Federation and External Access, and then click External Access Policy. Edit Global policy and enable federated user access.


Configure XMPP FEDERATED PARTNERS

SaslNegotiation NotSupported -EnableKeepAlive $false -
SupportDialbackNegotiation $true

Configure Skype For Business (SFB) User

Enable user for federation (define an external policy and assign it to the user). You don’t have to do it if you have enabled federation in global policy.

Configure Jabber for Federation

On Cisco Unified Presence Server, go to Presence Settings. Enable following settings in red.


Turn on "XMPP Federation Node Status" under General Settings (Presence => Inter-domain Federation => XMPP Settings).

Hi Ryan,

Office 365 supports federation with SFB 2015 or Lync setup. It doesn't support federation with non Microsoft platform. However, there are third parties (Nextplane etc) which helps you federate Jabber with Office 365.
