Chapter 2: Overview
• One port can be used to connect a 3G wireless Internet stick for failover support when VoIP and/or PSTN phone lines are not
available.
Reset button
Use the end of a paper clip to press the reset button.
• To restart the Hybrid PBX and VoIP Gateway, press and release the reset button. This is equivalent to disconnecting and then
reconnecting the power supply.
• To reset the Hybrid PBX and VoIP Gateway to factory default settings, press and hold the reset button until the first two FXO
lights on the left of the unit turn on.
Resetting to factory defaults erases all configuration settings. Auxiliary memory is not erased. When the Hybrid PBX and VoIP
Gateway restarts, the LAN ports will be set to the IP address 192.168.1.2. Any address configured on the WAN port is cleared.
Power connector
Connect the supplied power supply to this connector. The Hybrid PBX and VoIP Gateway does not have a power switch. It powers
up automatically when you connect the power supply.
CAUTION: Connecting any other power supply to this connector voids your warranty and may damage the Hybrid PBX and VoIP
Gateway.
Audio ports
The IPBX424 and IPBX1224 each have two mono mini-jack audio ports.
• Audio In: For connection of a music source for music-on-hold.
• Audio Out: For connection to a PA system for paging.
Ethernet ports
Both Hybrid PBX and VoIP Gateway models have four 10-/100-Mbps Ethernet ports with RJ-45 connectors. The ports are split
into the following two categories: LAN and WAN.
• LAN ports: Ports 1, 2, and 3 are LAN ports. These ports are generally used to connect the PBX to a local area network (LAN).
They can also be used to connect directly to a computer or SIP phone.
By default, the LAN IP address is set to 192.168.1.2.
For troubleshooting or system monitoring tasks, Port 3 can be switched into monitor mode, allowing it to capture all traffic on
Ports 1, 2, and 4.
• WAN port: Port 4 is called the WAN port. For certain installation scenarios, it can be used to connect the Hybrid PBX and VoIP
Gateway to the Internet or a private network that provides VoIP service.
NOTE: The LAN and WAN ports must have IP addresses on different networks.
NOTE: The Hybrid PBX and VoIP Gateway is not a router. It only forwards VoIP and voice traffic between its LAN and WAN ports.
This means that you cannot connect computers, SIP phones, or other IP-based devices to the Internet through the Hybrid
PBX and VoIP Gateway.
FXS ports
The FXS ports are used to connect the Hybrid PBX and VoIP Gateway to analog phone equipment, such as a telephone or fax
machine.
Failover support
The IPBX424 and IPBX1224 provide failover support on one FXS port. Thirty seconds after a power failure occurs, an FXS port is
automatically connected to an FXO line to enable calling from an analog phone.
