                                                    Verify that the caller ID standard (and substandard) of the device matches the standard of the PBX (using the parameters CallerIDType, BellcoreCallerIDTypeOneSubStandard, and ETSICallerIDTypeOneSubStandard). |

                                                    Verify that the correct FXO coefficient type is configured ([FXOCountryCoefficients] parameter in Analog Coefficient Types) because the device is unable to recognize caller ID signals that are distorted. |

                                                     | 
                                                    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.
