Discovered Partner Domain (Open Enhanced Federation) I'll discuss the main differences between them. Users really like Discovered Partner Domain federation because it's easy to use. Let's say that Sally wants to send IM messages to a new contact in a partner organization. She simply specifies the person's phone number (the Session Initiation Protocol Uniform Resource Identifier, or SIP URI) in her client's contact list. If that organization is setup for partner domain discovery, the person's name will appear in her contact list. She can then begin sending IM messages to that person. There is one caveat with this type of federation, though. There's a limit of 20 SIP messages received per second from a partner organization. With Discovered Partner Domain federation, Skype or Lync accepts any SIP domain name and uses DNS records to locate the partner organization's Access Edge server.

The partner organization needs to create two DNS records: What makes this possible is the interaction with the public DNS records that are created by the partner organization.

It should follow the format _sipfederationtls._. A DNS A record containing the Fully Qualified Domain Name (FQDN) of the Access Edge server.The port value for the SRV record should be TCP 5061.
