Reverse White Pages Lookup

When an inbound line has caller ID service from the CO, CIC can display the caller’s name to the user, or the caller’s name and address in the voicemail form, if you have the appropriate white pages directory data on the CIC server. CIC uses a Telephony tool, called WhitePages, to take the inbound caller ID number as input and do a lookup in a text file called WhitePages.txt installed in the \Resources directory on the CIC share. If it finds a match, the tool’s output is the caller’s name (in the case of a call answered with a CIC client), or the name and address, in the case of a voicemail message.

The format of the WhitePages.txt file, along with customization instructions, is explained in the default WhitePages.txt file installed with IC. The WhitePages tool is included in the handlers that manage incoming calls and voicemail. See WhitePages in the Interaction Designer online help.

While the capacity of the WhitePages.txt file is significantly greater than the Windows registry, this file is not designed to hold large volumes of directory data for caller ID lookup in IC. Each entry in the table requires overhead of approximately 100 bytes of memory, so the maximum reasonable number of entries recommended for the WhitePages.txt file depends in part on the CPU speed and amount of available RAM on the CIC server. On average, each CIC server should be able to support up to several thousand entries in the WhitePages.txt file, while high-end servers might support up to 10,000 entries, depending on the load on the server.
