Where can I find the link/pointers to each individual Call attachment?
All Call Ticket Attachment information is stored in the DB in a table named HEATGen. Each CallID that has an attachment is set as a row with a GCode column value of AT (for attachment) and a GName value of the actual CallID. The physical details for the Attachment (file name, location, etc.) is stored in that same row in the GDetail column.
In order to extract the file name and location, for example a specific CallID, you could run something similar to below. This is an example pulled from the demo DB for CallID 00000022:
The results in the GDetail column if pulled out would look like this:
