hrTel

hrTel is a software library and set of tools designed for parsing and manipulating telephony-related data, primarily call detail records (CDRs). It provides functionalities for reading various CDR formats, extracting specific fields, and transforming the data into a more usable structure. The primary goal of hrTel is to simplify the process of analyzing call data, which can be complex and often comes in proprietary or less standardized formats.

The library is written in Python and aims to be efficient and flexible. It supports parsing of common CDR formats and can be extended to accommodate custom or less common ones through its plugin architecture. Users can define schemas to map raw CDR fields to more descriptive names, making subsequent data analysis easier. hrTel can also perform basic data validation and cleaning.

Key features of hrTel include its ability to handle large volumes of CDR data, its support for different input sources such as files and databases, and its integration capabilities with other data analysis tools. The project is often used by telecommunication companies, network operators, and researchers who need to process and analyze call logs for billing, network monitoring, or statistical purposes. The project's development is community-driven, with contributions from individuals and organizations involved in the telecommunications sector.
