Parameter Description
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 = Interworking of CPC is performed
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
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.

[EnableCallerIDTypeTwo]
Disables the generation of Caller ID type 2 when the phone is
off-hooked. Caller ID type 2 (also known as off-hook Caller ID)
is sent to a currently busy telephone to display the caller ID of
the waiting call.
[0] = Caller ID type 2 isn't played.
[1] = Caller ID type 2 is played (default).
