Caller ID Parameters

The caller ID parameters are described in the table below.

Caller ID Parameters

Parameter

Description

'Enable Caller ID'

configure voip > gateway dtmf-supp-service supp-service-settings > enable-caller-id

[EnableCallerID]

Global parameter that enables Caller ID.

■ [0] Disable (default)
■ [1] Enable =
✔ CAS: The device detects the Caller ID signal received from the Tel and sends it to the IP in the SIP INVITE message (as the 'Display' element).

To configure the Caller ID string per port, see Configuring Caller Display Information. To enable or disable caller ID generation / detection per port, see Configuring Caller ID Permissions.

'Caller ID Type'

configure voip > gateway dtmf-supp-service supp-service-settings > caller-id-type

[CallerIDType]

Determines the standard used for generation (FXS) of Caller ID, and generation (FXS) of MWI (when specified) signals:

■ [0] Standard Bellcore = (Default) Caller ID and MWI
■ [1] Standard ETSI = Caller ID and MWI
■ [2] Standard NTT
■ [4] Standard BT = Britain
■ [16] Standard DTMF Based ETSI
■ [17] Standard Denmark = Caller ID and MWI
■ [18] Standard India
■ [19] Standard Brazil

Note:

■ The parameter is applicable only to analog interfaces.
■ Typically, the Caller ID signals are generated / detected between the first and second rings. However, sometimes the Caller ID is detected before the first ring signal. In such a scenario, set the [RingsBeforeCallerID] parameter to 0.
■ To select the Bellcore Caller ID sub standard, use the [BellcoreCallerIDTypeOneSubStandard] parameter. To select the ETSI Caller ID substandard, use the [ETSICallerIDTypeOneSubStandard] parameter.
■ To select the Bellcore MWI sub standard, use the [BellcoreVMWITypeOneStandard] parameter. To select the ETSI MWI sub standard, use the [ETSIVMWITypeOneStandard] parameter.
■ If you define Caller ID Type as NTT [2], you need to define the NTT DID signaling form (FSK or DTMF) using the [NTTDIDSignallingForm] parameter.

'Asserted Identity Mode'

asserted-identity-m

[AssertedIdMode]

Determines whether the SIP header P-Asserted-Identity or P-Preferred-Identity is added to the sent INVITE, 200 OK, or UPDATE request for Caller ID (or privacy). These headers are used to present the calling party's Caller ID, which is composed of a Calling Number and a Calling Name (optional).

■ [0] Disabled = (Default) P-Asserted-Identity and P-Preferred-Identity headers are not added.
■ [1] Add P-Asserted-Identity
■ [2] Add P-Preferred-Identity

The used header also depends on the calling Privacy (allowed or restricted). These headers are used together with the Privacy header. If Caller ID is restricted (i.e., P-Asserted-Identity is not sent), the Privacy header includes the value 'id' ('Privacy: id'). Otherwise, for allowed Caller ID, 'Privacy: none' is used. If Caller ID is restricted (received from Tel), the From header is set to <anonymous@anonymous.invalid>.

Digital Interfaces: The 200 OK response can contain the connected party CallerID - Connected Number and Connected Name. For example, if the call is answered by the device, the 200 OK response includes the P-Asserted-Identity with Caller ID. The device interworks (in some ISDN variants), the Connected Party number and name from Q.931 Connect message to SIP 200 OK with the P-Asserted-Identity header. In the opposite direction, if the ISDN device receives a 200 OK with P-Asserted-Identity header, it interworks it to the Connected party number and name in the Q.931 Connect message, including its privacy.

'Use Destination As Connected Number'

configure voip > sip-definition settings > use-dst-as-connected-num

[UseDestinationAsConnectedNumber]

Enables the device to include the Called Party Number, from outgoing Tel calls (after number manipulation), in the SIP P-Asserted-Identity header. The device includes the SIP P-Asserted-Identity header in 180 Ringing and 200 OK responses for IP-to-Tel calls.

■ [0] Disable (default)
■ [1] Enable

Note:

■ For this feature to function, you also need to enable the device to include the P-Asserted-Identity header in 180/200 OK responses, by setting the [AssertedIDMode] parameter to Add P-Asserted-Identity.
■ If the received Q.931 Connect message contains a Connected Party Number, this number is used in the P-Asserted-Identity header in 200 OK response.
■ The parameter is applicable to , ISDN and CAS interfaces.

'Caller ID Transport Type'

configure voip > media fax-modem > caller-ID-transport-type

[CallerIDTransportType]

Defines the device's behavior for Caller ID detection.

■ [0] Disable = The caller ID signal is not detected - DTMF digits remain in the voice stream.
■ [3] Mute = The caller ID signal is detected from the Tel side and then erased from the voice stream.

Note: This option is applicable only to Gateway calls.

■ [4] SetBySoftware = (Default) The behavior as defined for Mute is applied to Gateway calls. The behavior as defined for Disable is applied to SBC calls.
