Configure DNS details
Configure the DNS Server details
The “OCS gateway” Cisco VCS(s) should be configured to use the same DNS servers as OCS.
On the machine running OCS:
1. From the Windows Start menu choose Run.
2. Type cmd into the Open field and click OK. A command window opens.
3. In the cmd.exe window type:
ipconfig /all
4. Note down the DNS servers.
Note: If the DNS server IP address is 127.0.0.1 that means that OCS is using a DNS server on its
own hardware. Instead of entering 127.0.0.1 on the Cisco VCS, use the IP address of the OCS
platform instead.
On each “OCS gateway” Cisco VCS Control peer:
1. Go to the DNS page (System Configuration > DNS).
2. Set DNS Server Address 1 to the IP address of DNS server noted earlier.
3. If OCS has more than one DNS server defined, configure the remaining fields as follows:
DNS Server Address 2
IP address of DNS server 2 (if there is a second DNS server)
DNS Server Address 3
IP address of DNS server 3 (if there is a third DNS server)
DNS Server Address 4
IP address of DNS server 4 (if there is a fourth DNS server)
DNS Server Address 5
IP address of DNS server 5 (if there is a fifth DNS server)
4. Click Save.
