Domain Name
The Domain name is the name to append to an unqualified host name before querying the DNS server.
To configure the Domain name:
1. Go to System > DNS.
2. Configure the Domain name as follows:
 VCS Control VCS Expressway
Domain name
Enter internal-domain.net Enter example.com
3. Click Save.
The fully qualified domain name for the VCS Control is now vcsc.internal-domain.net
The fully qualified domain name for the VCS Expressway is now vcse.example.com
DNS Servers
The DNS server addresses specify the IP addresses of up to five domain name servers to be used for resolving domain
names. In either of the following cases you must specify at least one default DNS server for address resolution:
■ To use fully qualified domain names instead of IP addresses when specifying external addresses. For example,
for LDAP and NTP servers, neighbor zones and peers.
■ To use features such as URI dialing or ENUM dialing.
The VCS queries one server at a time. If that server is unavailable the VCS tries another server from the list.
In the example deployment two DNS servers are configured for each VCS, which provides a level of DNS server
redundancy. The VCS Control is configured with DNS servers which are located on the internal network. The VCS
Expressway is configured with DNS servers which are publicly routable.
To configure the Default DNS server addresses:
1. Go to System > DNS.
2. Configure the DNS server Address fields as follows:
 VCS Control VCS Expressway
Address 1
Enter 10.0.0.11 Enter 194.72.6.57
Address 2
Enter 10.0.0.12 Enter 194.73.82.242
3. Click Save.
