custom1 Format: This file format encodes CDRs according to the starent file format explained above.
Important:
The use of either starent or custom1 file formats, imposes a few specific
reactions: - files are generated without an extension; acknowledged and unacknowledged files are
differentiated by their file names; the system deletes all the files after reaching the maximum storage
period (1-7 days) configured during GSS configuration.

Important:
The use of either custom2 or custom3 file formats imposes the following actions:
- files are generated with the .u file extension (indicating an unprocessed file to the billing system); -
the GSS system deletes files with .p extension as part of periodic clean-up.
the GSS system deletes files with .p extension as part of periodic clean-up.
custom4 Format: This custom4 format was created to support writing CDRs in blocks. This file format is
similar to custom3 file format except CDRs will be written in 2Kbyte blocks in a file.
Header: No Header
