For Brazil Telecom
fxs-callid-cat-brazil
[AddCPCPrefix2BrazilCallerID]
Version 7.2
69. Configuration Parameters Reference

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.
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 the 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@10.20.7.3
5>;tag=53700
The calling number manipulation removes "+55" (leaving 10
digits), and then adds the prefix 7, the cpc code for
payphone user. Therefore, the Caller ID number that is sent
to the FXS port, in this example is 71137077801.
If the incoming INVITE message doesn't contain the 'cpc'
parameter, nothing is added to the Caller ID number.
