Debugging a Caller ID Detection on FXO
The following procedure describes how to debug caller ID detection on FXO interfaces.
|
➢
|
To debug a Caller ID detection on an FXO interface: |
|
1.
|
Verify that the parameter EnableCallerID is set to 1. |
|
2.
|
Verify that the caller ID standard (and substandard) of the device matches the standard of the PBX (using the parameters CallerIDType, BellcoreCallerIDTypeOneSubStandard, and ETSICallerIDTypeOneSubStandard). |
|
3.
|
Define the number of rings before the device starts the detection of caller ID (using the parameter RingsBeforeCallerID). |
|
4.
|
Verify that the correct FXO coefficient type is configured (see the CountryCoefficients parameter in Configuring FXS/FXO Coefficient Types), as the device is unable to recognize caller ID signals that are distorted. |
|
5.
|
Connect a phone to the analog line of the PBX (instead of to the device's FXO interface) and verify that it displays the caller ID. |
If the above doesn't solve the problem, you need to record the caller ID signal (and send it to AudioCodes), as described below.
|
➢
|
To record the caller ID signal using the debug recording mechanism: |
|
1.
|
Access the FAE page (by appending "FAE" to the device's IP address in the Web browser's URL, for example, http://10.13.4.13/FAE). |
|
2.
|
Press the Cmd Shell link. |
|
3.
|
Enter the following commands: |
dr
ait <IP address of PC to collect the debug traces sent from the device>
AddChannelIdTrace ALL-WITH-PCM <port number, which starts from 0>
Start
|
4.
|
Make a call to the FXO. |
|
5.
|
To stop the DR recording, at the CLI prompt, type STOP. |
