Add the Survivable Branch to the Lync Server Topology

Add the Survivable Branch to the Lync

Server Topology

As a CS Administrator, you must complete the following tasks before the SBM

is installed:

1. Define a branch site for the SBM’s site within a parent central site in the

Lync topology.

2. Add a Survivable Branch Appliance to the branch site, specifying the

SBM’s FQDN for the server FQDN and the PSTN FQDN.

Important You must specify the SBM’s FQDN for the PSTN gateway and not the SBM’s

IP address.

When you add the Survivable Branch Appliance, you can choose either

Transport Control Protocol (TCP) or Transport Layer Security (TLS) for

the Session Initiation Protocol (SIP) protocol, but TLS is strongly recom-

mended for security. You can specify any SIP port, but if you choose a non-

default port, you must tell the person who configures the SBM that you

have done so.

3. Publish the updated topology.

4. Set up voice routing policies and normalization rules for the branch site.

If desired, set up voice routing policies for other sites that egress traffic

through the SBM.

You can set up a variety of routing policies that egress PSTN calls through

the SBM’s PSTN connections and through PSTN gateways at other sites.

(The SBM automatically detects when a WAN failure prevents it from

using the remote PSTN gateways and adjusts the routing accordingly.)

Similarly, you can route calls from the central site through the SBM. In

this way, you can optimize your system for the lowest-cost and most

efficient communications. In addition, you can create backup routes that

ensure that users can always reach who they need to when they need to.

Remember also to establish valid normalization rules for the branch site.

You can use the global dial plan to dictate these rules, or you can create

a new plan.
