Configuring SIP: Blocking Caller ID Information Globally When Privacy Exists
The Call-ID information is private information. In ISDN there is a private setting that can be set to
protect this information. However, whenever SIP gets the Call-ID information, it does not hide the
private information, rather, it just sets a field to reflect that it is private and not to display it on a Call-ID
display. But, the data is still viewable in the SIP message requests. This option allows the Cisco gateway
to delete the Call-ID information from the SIP message requests so it cannot be read on the network.
