Each edge server has one or more of the following roles: Access Edge Server, Web Conferencing Edge Server, or A/V Edge Server. |
Enhanced federation |
In Live Communications Server 2005, an organization-to-organization federation that uses DNS-SRV resolution to identify the Access Proxy for each partner. In Office Communications Server 2007, this term is not used. You can achieve this functionality to configure your Access Edge Server to use DNS to automatically discover federated partners. |
