User's Manual
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.
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>;t
ag=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.
