User's Manual 1190 Document #: LTRT-10632
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.
