Corporate

Corporate means in this context that the IP-network is an enterprise network with IP connection between the different sites in the network. The visitor's extensions must be able to address the home site system/network via SIP (and HTTP) or H.323 signaling.

Log-on or Log-off

Log-on is the same as Registration or Roaming for an IP extension. Registration means authorization that the terminal is allowed to log on to the system and the actual acknowledgment of the terminal in the system, making the terminal known by the system.

Log-off is the same as De-registration for an IP extension.
