Node election rules

A Signaling Server with Virtual Trunks configured wins an election because
it registers on the NRS with an IP node. Because the IP node could be
provided to a Branch Office system during redirection to normal mode or to
another CS 1000 peer system during Network wide Virtual Office logon, the
TPS application must be enabled on the Signaling Server which is running
the VTRK application.
The rules for the node election process are as follows:
1. A Signaling Server wins over any Voice Gateway Media Cards.
2. A Leader card always wins over a Follower card.
3. Media Card 32-port card wins over an ITG-P card but the Media Card
4. Within each class (Leader/Follower), the card with the longest uptime
5. In the event of a tie in uptime length, the card with the lowest IP address
The precedence of the rules is from 1 (highest) to 5 (lowest).
