  Mediant 800B Gateway & E-SBC 
Parameter  Description 
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@10.20.7.35>;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.
