Debugging A Caller Id Detection On Fxo - AudioCodes Mediant 1000 User Manual

The configuration for Caller ID is described below:
Use the parameter CallerIDType to define the Caller ID standard. Note that the Caller
ID standard that is used on the PBX or phone must match the standard defined in the
device.
Select the Bellcore caller ID sub standard using the parameter
BellcoreCallerIDTypeOneSubStandard
Select the ETSI FSK caller ID sub standard using the parameter
ETSICallerIDTypeOneSubStandard
Enable or disable (per port) the caller ID generation (for FXS) and detection (for FXO)
using the 'Generate / Detect Caller ID to Tel' table (EnableCallerID). If a port isn't
configured, its caller ID generation / detection are determined according to the global
parameter EnableCallerID.
EnableCallerIDTypeTwo: disables / enables the generation of Caller ID type 2 when
the phone is off-hooked (used for call waiting).
RingsBeforeCallerID: sets the number of rings before the device starts detection of
caller ID (FXO only). By default, the device detects the caller ID signal between the
first and second rings.
AnalogCallerIDTimimgMode: determines the time period when a caller ID signal is
generated (FXS only). By default, the caller ID is generated between the first two
rings.
PolarityReversalType: some Caller ID signals use reversal polarity and/or wink
signals. In these scenarios, it is recommended to set PolarityReversalType to 1 (Hard)
(FXS only).
The Caller ID interworking can be changed using the parameters
UseSourceNumberAsDisplayName and UseDisplayNameAsSourceNumber.

7.14.7.2 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
