Not directly, but you can use xml_curl to query a web server which queries a database:

Subject: [Freeswitch-users] Can FS use external user database

Gurus,

Can we configure FS to have it to read registeration users information (e.g. account and pwd) for authentication from external database replacing default xml files(under conf\directory\default)?

e.g. we have a database which contains user's account and password and was used by other application, we would like to have FS to read this exsiting databse for authentication as well...

Thanks.

Regards,
Charles
