The feature is applicable only to analog interfaces.
Enabling Caller ID Generation and Detection on Tel Side
The device's Caller ID support depends on the type of analog interface:
â– FXS interfaces: The device sends (generates) the Caller ID signal to the device's FXS port.
â– FXO interfaces: The device detects the Caller ID signal from the FXO port.
You can enable Caller ID generation (FXS interfaces) and detection (FXO interfaces)
per port in the Caller ID Permissions table (see Configuring Caller ID Permissions). For
ports that are not configured in the table, Caller ID is according to the global parameter,
as described in the procedure below.
The following procedure describes how to enable Caller ID for all analog ports.
➢ To enable Caller ID:
1. Open the Supplementary Services Settings page (Setup menu > Signaling & Media tab >
Gateway folder > DTMF & Supplementary > Supplementary Services Settings).
2. From the 'Enable Caller ID' drop-down list (EnableCallerID), select Enable.
3. Click Apply.
Additional Caller ID parameters includes the following:
â– CallerIDType: Defines the Caller ID standard. The configured standard Caller ID must match
the standard used on the PBX or phone.
â– BellcoreCallerIDTypeOneSubStandard: Defines the Bellcore Caller ID sub-standard.
â– ETSICallerIDTypeOneSubStandard: Defines the ETSI FSK Caller ID sub-standard.
â– EnableCallerIDTypeTwo: Enables generation of Caller ID type 2 when the phone is off-
hooked (used for call waiting).
â– RingsBeforeCallerID: (FXO interfaces only) Defines the number of rings before the device
starts detection of Caller ID. By default, the device detects Caller ID between the first and
second rings.
â– AnalogCallerIDTimimgMode: (FXS interfaces only) Defines the time period when a Caller
ID signal is generated. By default, Caller ID is generated between the first two rings.
â– PolarityReversalType: (FXS interfaces only) Defines reversal polarity and/or wink signals for
Caller ID signals. It is recommended to configure the parameter to 1 (Hard).
â– UseSourceNumberAsDisplayName and UseDisplayNameAsSourceNumber: Defines
Caller ID interworking.
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.
