Mediant 600 & Mediant 1000
Parameter Description

[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, configure
the parameter RingsBeforeCallerID 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 parameter
BellcoreCallerIDTypeOneSubStandard. To select the ETSI Caller
ID substandard, use the parameter
ETSICallerIDTypeOneSubStandard.
 To select the Bellcore MWI sub standard, use the parameter
BellcoreVMWITypeOneStandard. To select the ETSI MWI sub
standard, use the parameter ETSIVMWITypeOneStandard.
 If you define Caller ID Type as NTT [2],
you need to define the NTT
DID signaling form (FSK or DTMF) using the parameter
NTTDIDSignallingForm.
Web: Enable FXS Caller ID
Category Digit For Brazil
Telecom
[AddCPCPrefix2BrazilCalle
rID]
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=53
700
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.
