Version 6.6 521 MP-11x & MP-124
User's Manual 43. Configuration Parameters Reference
Parameter Description
If the Caller ID service is enabled, then for FXS interfaces,
calling number and Display text (from IP) are sent to the
device's port.
For FXO interfaces, the Caller ID signal is detected and sent to
IP in the SIP INVITE message (as 'Display' element).
For information on the Caller ID table, see Configuring Caller
Display Information on page 268.
To disable/enable caller ID generation per port, see
Configuring Call Forward on page 270.

EMS: Caller id Types
[CallerIDType]
Determines the standard used for detection (FXO) and
generation (FXS) of Caller ID, and detection (FXO) / 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
Notes:
 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.
 Caller ID detection for Britain [4] is not supported on the
device’s FXO ports. Only FXS ports can generate the Britain
[4] Caller ID.
 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.
Web: Enable FXS Caller ID
Category Digit For Brazil Telecom
[AddCPCPrefix2BrazilCallerID]
Enables the interworking of Calling Party Category (cpc) code
from SIP INVITE messages to FXS Caller ID first digit.
 [0] Disable (default)
 [1] Enable
When this parameter is enabled, the device sends the Caller ID
number (calling number) with the cpc code (received in the SIP
INVITE message) to the device's FXS port. The cpc code is
added as a prefix to the caller ID (after IP-to-Tel calling number
manipulation). For example, assuming that the incoming
INVITE contains the following From (or P-Asserted-Id) header:
From:<sip:+551137077801;cpc=payphone@10.20.7.35>;
tag=53700
