ODBC in the core
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 using ODBC.
