Cisco WebEx federation with other instant messaging providers

Cisco WebEx can federate with users of leading instant messaging providers such as AIM, IBM Lotus Sametime, Microsoft Lync, and XMPP-based IM networks like GoogleTalk and Jabber.org. A list of public XMPP-based IM networks is available at the XMPP Standards Foundation website: http://xmpp.org/services.

Federation requirements

This section provides information on federating Cisco WebEx version 6.x and later with several leading IM providers.

Federating with the AOL Instant Messaging network

Cisco WebEx can federate with AOL’s instant messaging network. Contact your Cisco WebEx account representative if you would like to federate with AOL’s instant messaging network.

Federating with IBM Lotus Sametime

Federation between Cisco WebEx and IBM Lotus Sametime requires the IBM Lotus Sametime XMPP Gateway to be configured and running in the IBM Lotus Sametime environment and the publishing of a XMPP service (SRV) record in DNS for your domain. IBM Lotus Sametime XMPP Gateway is available from IBM.

For example, if your domain is acme.com and the IBM Lotus Sametime domain you want to federate with is mysupplier.com, you will need to publish a XMPP Service record for your domain, acme.com in DNS. For more information, refer to Specifying IM Federation settings. The owner of the mysupplier.com domain will need to configure and run the IBM Lotus Sametime XMPP gateway in their environment.

Federating with Microsoft Lync

Federation between Cisco WebEx and Microsoft Lync requires an XMPP Gateway to be configured and running in the Microsoft environment and the publishing of a XMPP service (SRV) record in DNS for your domain. Additionally, confirm that TCP Dialback is set in the XMPP Configuration settings on the XMPP Gateway server. Microsoft Gateway is available from Microsoft.

For example, if your domain is acme.com and the Microsoft domain you want to federate with is mysupplier.com, you will need to publish a XMPP Service record for your domain acme.com in DNS. For more information, refer to Specifying IM Federation settings. The owner of the mysupplier.com domain will need to configure and run the Microsoft XMPP gateway in their environment.

Federation with XMPP-based IM networks or IM solutions that support XMPP

Federation between Cisco WebEx and XMPP-based Instant Messaging networks or IM solutions that support XMPP requires the publishing of a Service (SRV) record in DNS. Examples of XMPP-based IM networks include Google Talk, and Jabber.org. For more information on enabling XMPP federation, refer to Specifying IM Federation settings.

The following example shows how XMPP federation is provisioned for an organization called Acme.com.

If acme.com wants federation with external domains (domains not within the Cisco WebEx Collaboration cloud), it publishes the following Service (SRV) records in DNS:

_xmpp-server._tcp.acme.com. 86400 IN SRV 5 0 5269 s2s.acme.com.webexconnect.com

 

 

Notes:

 

 

  • The SRV records for your domain can be found in IM Federation under the Configuration tab. For more information, see Specifying IM Federation settings.
  • The TCP port, 5269 should be open to enable XMPP federation.

 

Configuring a DNS server sample

The following are sample IM Federation settings for each of the options available:

  • SRV (Service):
  • Service = _xmpp-server
  • Protocol = _tcp
  • Name = acme.com (domain name)
  • Priority = 5
  • Weight = 0
  • Port = 5269
  • Target = s2s.acme.com.webexconnect.com
