Hello guys,

I am trying to minimize the footprint of FreeSWITCH runtime and remove un-needed modules and their libs. This modules is not mentioned any where and not much on the web. Could u please provide more info on what functionalities it provides?

I'm planning to use FreeSWITCH for only SIP/sofia and Jingle/gtalk.

Thanks,

It is used to handle file formats to generate email of voicemail. I am using it and it works fine. I handles different file formats. I am using aaif to send voicemails to an iPhone. Here they are: http://wiki.freeswitch.org/wiki/Mod%5Fplayback#mod%5Fsndfile

It provides support for reading most of the sound file formats that FS supports. Almost anything that involves a sound file (e.g. voicemail, playback, IVR, record etc) requires it. It isn't necessary if you're just routing calls between endpoints, but anything more complex probably requires it.

February 2020 : added config file for mod_sndfile (sndfile.conf.xml) which currently has only one param called "allowed-extensions" which allows to configure only certain file extensions to be loaded. Eg: <param name="allowed-extensions" value="wav,raw,r8,r16,ogg"/>
