allows for failover and fallback functionality with a
secondary proxy server. For example:
For SRV Record:
sip.server.com:SRV=node1.sip.server.com
:5060:p=1:w=50|node2.sip.server.com:506
0:p=2:w=50

no.
For A Record:
sip.server.com:A=172.20.2.1,172.20.2.2
Set Use DNS SRV to no and DNS SRV Auto Prefix to
no.
