response of the primary server during heartbeat threshold time, it will
switch to secondary server.

Once the primary server recovers normal and responds heartbeat
messages, VGW will switch back to it again.

In "Register" mode, whether it is switched or not between primary and
secondary server, it is decided by response of registration or invite
messages. Firstly, VGW sends registration messages to primary server. If
the server doesn't respond for 3 times continuously, VGW will switch to
secondary server. Switching from secondary server to primary is the same
mechanism. When VGW has registered to soft switch for 3 times with no
response of invite messages, VGW will switch to another server. In
"Register" mode, primary and secondary servers are parallel in
relationship, meaning it will only switch when the server gets a breakdown.
