Add the Survivable Branch to the Lync Server Topology
Figure A-22. Lync Server 2010 Topology Builder > Define New Survivable Branch
Server—Select an Edge Server Page
13. If your site provides remote access, select the Edge pool at the central site
that the branch site will use, and click Next.
14. For Gateway FQDN or IP address, type the same SBM FQDN that you
specified for the survivable branch appliance.
Note You must specify the SBM’s FQDN, not its IP address.
15. Select the SIP Transport Protocol. It is recommended that you select TLS,
which provides encryption.
16. The Listening port for PSTN gateways field fills in automatically based on
the selected protocol. You can change this setting if you want, but you
must inform the technician installing the SBM, so he or she can specify
the same port. The default port in this wizard matches the default port in
the SBM Setup Wizard.
