This document provides information about the capacities and capabilities of IP Office R12.2 to help with high level design.

• The most complex single component to consider is generally the IP500 V2 when acting as a expansion system in a Linux-based primary server network, due to its combination of VoIP, digital and analog phones/trunks.

• The Linux-based server components (primary server, secondary server, and Linux-based expansions) are IP only and single construct, save for the decision whether to move the one-X Portal server from the primary to a separate platform (an IP Office Application Server) for capacity.

IP Office releases prior to R12.2 have differing capacities and performance limits. Therefore, for those systems refer to the corresponding release documentation.
