Description: FreeSWITCH is a scalable telephony platform designed to route and interconnect popular communication protocols using audio, video, text, or any other form of media. FreeSWITCH can perform full video transcoding and Multipoint Control Unit (MCU) functionality. Additionally, this technology supports many advanced Session Initiation Protocol (SIP) features such as presence/ Busy Lamp Field (BLF)/ Service Level Agreement (SLA) as well as Transmission Control Protocol (TCP) Transport Layer Security (TLS) and Secure Real-Time Transport Protocol (sRTP). This technology can also be used as a transparent proxy with and without media in the path to act as a Session Border Controller (SBC) and proxy T.38 (International Telecommunication Union (ITU) recommendation for allowing transmission of fax over Internet Protocol (IP) networks in real time) and other end-to-end protocols.

The FreeSWITCH core provides the Application Programming Interface (API) for modules to make connections to databases. FreeSWITCH currently supports the following Data Source Name (DSN) types: PostgreSQL, Open Database Connectivity (ODBC), and SQLite. The default FreeSWITCH configuration uses a series of SQLite databases that are stored in the /usr/local/freeswitch/db directory of a FreeSWITCH installation. This configuration can be changed to connect to other databases such as ODBC-compliant databases. Freeswitch supports ODBC, enabling various aspects of a system configuration and state to be stored within a database. SIP registrations, call/ channel state, voicemail messages, and voicemail preferences may be stored in the database. Additionally, mod_limit configuration, mod_nibblebill, and call detail record information may be stored in a database.

Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
