IP Phone boot-up service

1. Obtain Voice VLAN info.
2. Request DHCP information. The DHCP Server sends
   the IP address of the TFTP server to the IP
   phone.
3. The IP phone then contacts the TFTP server to get
   a configuration file. The configuration file
   specifies the list of CallManagers to which the
   IP phone should attempt to register.
4. The IP phone then attempts to register the
   primary CM. If connection failed, the IP phone
   will try the subsequent servers from the list
   that was provided by the TFTP server.

Database Clustering

• The database is a Microsoft SQL Server
• If the database resides on a single machine,
  phone network would be vulnerable to a machine
  outage.
• Each CallManger cluster consists of a set of
  networked databases
• Publisher Provides read and write access for
  database administrators and CallManager nodes
  themselves.
• Subscriber Read-Only. CallManger nodes access
  the subscriber databases only in cases when the
  Publisher is not available
