The following table is a summary only. Support for particular types of extension, trunk and user ports also depends on other factors such as local support variations. For example, BRI trunks are not supported in North American locales.

1.100 Extensions in 3-digit extension numbering mode. 48 extensions in 2-digit extension numbering mode.
•For IP Office Basic Edition modes, the system assumes that the base control unit is always fully populated with up to 32 extensions, either real or phantom or a mix, to which it assigns extension numbers in sequence.
oIt does this before assigning extension numbers to any real extensions on attached external expansion modules up to the system extension limit. If the system extension limit has not been exceeded, any remaining extension numbers are assigned to additional phantom extensions.
2.In all modes, voice compression hardware resources are also required for SIP support.
3.IP Office Basic Edition mode systems do not support BRI and PRI trunks in the same system. They are also restricted to 12 BRI channels regardless of the BRI hardware installed.
4.IP Office Basic Edition mode systems are limited to 1 x single-port PRI card.
5.Capacity is dependent on licenses, voice compression resources and available bandwidth.
