The VOI-9200 IP PBX is an embedded Voice over IP (VoIP) Server with Session
Initiation Protocol (SIP) to provide global virtual office IP extension phone connection
for small-to-medium business (SMB) companys. Equipped with two FXS ports,
two FXO ports, Ethernet LAN and WAN ports, VOI-9200 combines the telephony
network and the data network into a manageable converged network.
VOI-9200 IP PBX works with various IP phones (Desktop, WiFi, Bluetooth, and
DECT), VoIP gateways, and analog telephone adapters (ATA) to route calls among
client phones, analog phones, and PSTN network. Call features such as
conferencing, auto attendant, and voicemail can be seamlessly enabled to all phone
devices. In addition, it also provides Internet access to all LAN devices through NAT
router.
VOI-9200 IP PBX provides call control and media relay services to SIP clients, and it

than building separated infrastructures for legacy telephony network and data
network. In addition, with a web-browsable interface to the data network configuration
and voice service provisioning, VOI-9200 brings the manageability of both networks
together to facilitate administration locally or remotely.
