Internal pool fully qualified domain name (FQDN) of the Edge Server pool. Edit the FQDN of the pool to change this setting.

Select the check box Enable federation for this Edge pool (Port 5061) if you will setup federation with a Microsoft Lync Server 2010, Microsoft Office Communications Server 2007 or Microsoft Office Communications Server 2007 R2 trusted partner.

Select A/V Edge service is NAT enabled if you will use network address translation (NAT) for the Audio/Video Edge service.

In Features and Functionality, you define what additional roles that this pool will have collocated on its member servers. You can select from the following:

• Conferencing, which will include audio, video and application sharing. After you select this option, you can select Dial-in (PSTN) conferencing. You can specify and define a PSTN gateway later under Mediation Server settings.
  
  
• Enterprise Voice, which will enable internal voice over IP calls to qualified Lync Phone Edition handsets and devices and Microsoft Lync 2010 clients. External call capabilities are enabled by inclusion of a Mediation Server that is enabled later in the Mediation Server section.
  
  

Set the value Internal Configuration Replication Port (HTTPS) to the TCP/IP port number that the Edge Server’s local copy of the Central Management store will use to replicate changes from the read/write copy of the database. The default value is 4443.

To set or modify the Next hop pool that the Edge Servers will use to communicate to the internal Lync Server 2010 infrastructure, select a Director, Director pool, Front End Server or Front End Server pool from the dropdown. Only Directors or Front Ends that have been configured in Topology Builder will appear for selection.

To edit or specify settings for the External Settings for the Edge Servers, you first must determine if you will use separate IP addresses for SIP access, web conferencing and the Audio/Video service.

If you intend to use separate IP addresses for each, select the check box Enable separate FQDN and IP address for Web conferencing and A/V. Each service must have a corresponding DNS host (A) record created for it.

For each of the external-facing services, you specify a FQDN and an associated port. For example, the SIP Access would use sip.contoso.com with an associated port of 5061.

Important:

If you select separate FQDNs for each of the external-facing services, each service must have a unique port value associated with it. By default, the SIP is on port 5601/TLS, the web conferencing edge service is on port 444/TLS, and the A/V Conferencing Server is on port 443/TLS. If you make changes to any of these settings, including using separate FQDN and IP addresses or ports, you must update all other services that would rely on the initially configured values.

If you determine that your organization will use a single FQDN and IP address for the external-facing services, you clear the Enable separate FQDN and IP address for Web conferencing and A/V check box. You can then edit the SIP Access pool FQDN and port values, if necessary.

Important:
If you make changes to any of these settings, including using separate FQDN and IP addresses or ports, you must update all other services that would rely on the initially configured values.
