The Polycom® OBi302 is a single port FXO and single port FXS Analog Telephone Adapter (ATA) device packaged in a compact chassis. This device can be used for the following purposes:

Analog Backup line for incoming and outgoing calls on FXO port
Fax machine on FXS port
Local or remote phone on FXS port

The FXO and FXS ports operate independently of each other. For example, the OBi312 can provide phone or fax service on the FXS port while simultaneously providing an analog back up connection on the FXO port.

Overview of the Installation Process

The OBi312 is normally pre-configured for use with our Business Voice+ telephone system. In most cases, the installer can connect the OBi312 to the customer’s network along with the appropriate analog telephone connections.

Connecting the OBi312

The rear panel of the OBi312 has a power connection, USB connection, two RJ11 telephone connectors, and two RJ45 network connectors, as shown in the following picture:

The connectors are used as follows:

Connector	Purpose
Line	Connection for an FXO (Office) device, usually an analog phone line for backup operation.
Phone	Connection for an FXS (station) device, such as an analog telephone or a fax machine.
USB	Not supported with Business Voice configurations.
LAN	Connection for a laptop computer. Use this connection for off-site configuration.
Internet	Connection to the local network (if used as a local device) or to a WAN connection (if used as a remote device).
DC 12V Power	Power connector. Connect the provided AC power supply here. Note: Does not operate on Power over Ethernet (PoE).

The LAN port is only used to access the OBi312’s built-in configuration server from a connected laptop. This is necessary when performing off-site configuration. After the device is configured, the LAN cable can be disconnected.

Pre-Installation Configuration

Ensure that the OBi312 device is added to the customer system correctly using the portal. ATA devices are added via the Multi-Extension Devices page in the portal. Analog Phone and Fax Extensions are configured via the Extensions page in the portal. Analog backup is configured via the Analog Backup / Operator page in the portal. For more information, refer to the ATA Portal Configuration Guide.

The OBi312 can be configured for either local (On-Net) or remote (off-net) use. If you are re-deploying an OBi312 that was already configured, follow the instructions in the Factory Reset section below. Then, configure the device for either local or remote operation.

If you are unsure about the current configuration, perform a factory reset, and then configure the device using the ATA Portal Configuration Guide.

Factory Reset

To factory reset the OBi312 ATA device:

Unplug the cable from the WAN or LAN port.
Locate the small raised hole on the bottom of the unit, near front left corner.
Insert a straightened paper clip or other thin tool into the hole, and press for about ten seconds. Once removed, the device resets to the factory settings

Configure as a Local Device

To configure the OBi302 ATA device as a local device:

Connect the WAN port to the telephony switch, which is the switch connected to LAN2 and LAN3 on the

StarBox^® Voice Optimized SD-WAN.

Connect power supply. The device automatically downloads configuration and completes registration. Once registered, the OBi302 can make and receive inbound and outbound calls.

Note: Automatic configuration download only applies to the standard StarBox installation.

Configure as a Remote Device

The OBi312 can operate as a remote device, but it requires installation-specific configuration information to operate. For assistance, contact Sangoma’s Technical Support.
