The QX2000 is designed for offices of up to 2,000 users supporting up to 300 concurrent calls
to/from external networks. Since this system is a pure IP telephone system, QX Gateways should be
added for analog or digital ports including FXS, FXO, ISDN, BRI, E1, PRI and TI. The QX2000 can
connect to the PSTN via the added Gateways or directly to an ITSP.
