Hold the reset button. After a few moments the four LEDs of the display will start to blink. Only when all the
four LEDs stop blinking, release the reset button and wait for the light of the LEDs to go out. Then unplug
the power and retest the device.
In case the operation was not successful, repeat it again.
Test procedure (performed after the device is reset)
For the test performance you need:
1 PBX with a user (you can create a new user especially for the test or use an existing one)
1 provisioned phone associated to this user
1 Dialplan procedure
1 provisioned BRI device (which was previously reset and upgraded to the latest version of firmware)
1 network cable to connect the ports involved in the test
The test
The test consists of a call with two ports involved, one used as outgoing, another one – as incoming.
The PBX plays the audio file in loop to keep the call running and give the possibility to test the device.
It is recommended to perform this operation in a specifically designed test environment in order to exclude the
problems caused by some external factors, that could influence the result (the problems related to the operator,
lines, configuration etc).
The following logical scheme demonstrates the procedure. In this case W02BRI is used (in case W01BRI is
tested, you need another BRI device, to set up the second port):
