IP500 V2 control units can support 384 users and up to 384 extensions (analog, digital, H.323, SIP, or DECT). Analog and digital extension capacity is dependent upon the hardware fitted to the system.
Maximum users and extensions are configuration limits as well as a currently active/registered limit.
Extension and user limits include any resilience fail-over extensions/users; again these are configuration limits as well as a currently active/registered limit.
Extension capacity support includes IP Office acting as a server for any DHCP, upgrade and other operational files. 1600/9600/J100 phone upgrade performance is limited to 50 within 50 minutes for the same phone type.
Upgrading more than 50 phones at a time from an IP500 V2 is not recommended. If upgrade performance above these figures are required, an external HTTP/S server can be used.
For non-subscription systems, H323, DECT, and SIP extension capacity is also limited by available licenses.
9600 H323 Remote worker extensions are supported at a lower capacity; maximum 120.
9600 H323 extensions with TLS are supported at a lower capacity; maximum 128. Each extension using TLS counts as 3 extensions for IP500 V2 capacity planning.
