Installing sipXecs can be done in two different ways: a) using a sipXecs installation CD, which installs everything including the operating system, or b) using  application RPMs that can be installed after the operating system is already running using packet management.  The installation CD is based on CentOS and features automated installation of both the application and the operating system. System configuration is done using a graphical configuration wizard.

The installation wizard allows automated configuration of a high-availability system with two servers operating in load-sharing redundant mode.  In addition, the installation wizard offers to configure additional network services such as DHCP, DNS, and NTP on the host. sipXecs requires correct configuration of these services in order to operate properly. If external DHCP, DNS and NTP services are used make sure you follow the directions on the Wiki on how to set them up. As a new feature in the 3.10 release sipXecs offers a built-in test suite invoked from the Web administration UI that allows testing of properly configured network services. Use it to make sure everything is OK.

Minimum system requirements for a production server are P4 or Core 2 Duo CPU, 1 GB RAM, 80 GB HD. Test systems can work with less. The server needs to be given a fixed IP address and hostname that resolves in DNS. 

Usually there are no special requirements imposed on the LAN infrastructure. Setting up QoS or VLANs is usually not required, but you do need a 100 Mbit/s switched environment. A wired infrastructure is clearly superior to wireless (WiFi), unless you have a very new WiFi deployment based on the 802.11n standard.  The 802.11g standard only provides 54 Mbit/s peak shared across all users connected to the access point and only half-duplex.

The sipXecs installation CD installs a standard CentOS based system. System administration after installation can be done using all the usual procedures and tools to administer such a system. In particular, updates to the system's operating system and the sipXecs application are done with the standard package management system. The sipXecs application includes logic to provide for automated upgrades between major releases (i.e. database migration and other configuration).
