The mod_httapi in FreeSWITCH allows you to upload your call recordings to a HTTP server, in my case I’ve put together a Flask based Python server for a project I’m working on, which when the call ends, uploads to my web server. Presto!

<action application="record" data="http://(file=recording.wav,name=part1.PCMU,method=POST)your_domain.com/recording_upload"/>

Obviously you’ll need to replace the URL etc, but you can then just extract the POSTed file out and boom, you don’t need to store any recordings on each FreeSWITCH instance.

This is fantastic if you’re running multiple instances in a cluster or containerized, and want every FreeSWITCH instance to be dumb and with access to the same data as every other instance.
