REX8000 IP-PBX

General Description:
REX8000 IP-PBX can provide a converged solution package of telecommunication (including audio calls, video calls, high-speed fax, telephone conferencing, call recording, and mobile extensions). It satisfies the demand for a distributed network of over 10,000 extensions throughout government agencies and business groups, both of which require at least 1,000 extensions per site. REX8000 supports access for 10,000 users with 800 concurrent calls, demonstrating its powerful call processing capacity. This outstanding performance even extends to its stability, reliability, security, expandability, configurability, and more.

REX8000 meets various telephony requirements, including deployment at a single site of large- and medium-size enterprises, as well as a multi-site telephone network of large corporations and government agencies via internet/VPN. This is made possible by supporting direct connection with carriers via SIP trunk (including IMS), or connection with the carriers or other audio private networks via digital trunk① or analog trunk②, as well as connection to analog telephones, fax machines, POS , IP phones, video phones, softphones on PCs/cellphones/PADs.
