14.7.6.2. Branch Example with Geo-Separated OpenScape Voice and TLS 
In branch scenarios (with Survivability-Proxy, e.g. OpenScape Branch
or Comdasys) you can have two DNS server entries, one for the local branch-proxy
and a central one. Specify the DNS servers in AMO CGWB under parameters
DNSIPADR and DNSIPADR2. In this example the network only
has one DNS server.
DNS-SVR-records:
br08a2.st.lz.com leads to:
Branch-proxy
Sipsm3 on node1
Sipsm4 on node2.
nd08a.st.lz.com leads to:
Sipsm3 on node1
Sipsm4 on node2.
