7.13.7.2 Debugging a Caller ID Detection on FXO

To debug a Caller ID detection on an FXO interface, take these 7
steps:
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 (CallerIDType, BellcoreCallerIDTypeOneSubStandard, and
ETSICallerIDTypeOneSubStandard).
3. Define the number of rings before the device starts detection of caller ID
(RingsBeforeCallerID).
4. Verify that the coefficient file loaded to the device is correct (if the caller ID signal is
distorted, the device won't recognize it).
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.
6. Configure the following parameters:
•
FXOSeizeLine = 0
•
RTPOnlyMode = 1 (or 2) - the RTP is sent without SIP signaling
•
Coder G.711
•
In the 'Tel to IP Routing' table, route all calls to the PC used for capturing
•
EnableCallerID = 0
•
RingsBeforeCallerID = 0
•
Set the automatic dialing to hotline (e.g., TargetOfChannel7 = 9005,2)
•
HotLineToneDuration = 0
The above settings allow the FXO to send RTP without immediately seizing the line
after receiving the first ring at your PC.
7. Capture the RTP using Wireshark (you can also use DSP trace) and send the file to
AudioCodes.
