You are employed as a administrator at ABC.com. ABC.com network has an Active Directory
domain, named ABC.com. ABC.com’s network includes a Lync Server 2013 setup.
You have configured a single Enterprise Edition pool, and have activated Enterprise Voice for all
ABC.com Lync users. ABC.com’s PSTN gateway does not support secure signaling, and you have
configured the Not Supported setting as the encryption support level for the global trunk setup.
After including an additional PSTN gateway, you set the SIP transport type to TLS. You then set
the SIP UDP local port and the SIP TCP local port to port 5060. You have also set the SIP TLS
local port to port 5067, and disabled SIPS.
You have created and installed a certificate, via an internal certification authority (CA), on the
second PSTN gateway. You are then instructed to make sure that both PSTN gateways are
usable by Lync Server 2013 for making calls on the PSTN.
You start by creating another PSTN gateway via the Topology Builder.
Which of the following actions should you take NEXT?
A.
You should consider generating a new trunk configuration for the second PSTN gateway.
B.
You should consider setting encryption support level for the global trunk setup to Required.
C.
You should consider publishing the topology.
D.
You should consider setting encryption support level for the new trunk setup to Not Supported.
