The IT staff will pay a lot of attention to servers, switches, routers, and network security when planning for VoIP deployments. The core IT network services in Miami, which allow users to access all these amazing systems and are essential for VoIP to work at all, receive almost no attention.
For users to be able to access their applications, there are four core network services they must have up and running. These services are:
DHCP stands for Dynamic Host Configuration protocol. This service gives the user an internal network IP address when they connect. Without an IP address, network communication cannot take place. This information includes the default route and IP addresses of DNS servers.
DNS stands for Domain Name Service. This service is responsible for translating easy-to-remember names, such as URLs, onto the IP addresses required by the applications on computers. Any network-based application cannot be used without DNS. DNS is typically provided by redundant windows servers and externally by small Linux boxes running the BIND operating system.
NTP stands for Network Time Protocol. Many applications require time on servers and workstations. These include SIP-based voice applications, network security applications, and SIP-based voice apps. NTP can be served in many cases from redundant windows servers.
