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
