Hi All. We have a unique requirement (I think)... We need to stream the media to another server for analysis while the call is taking place. So, basically, real-time analysis. Can somebody point me in the right direction?

You could try mod_audio_fork:

https://github.com/drachtio/drachtio-freeswitch-modules/blob/main/modules/mod_audio_fork/README.md

you will need to build a custom freeswitch version with libwebsockets support (https://github.com/drachtio/drachtio-freeswitch-modules).

But if you are stuck with an existing version of freeswitch, you could use mod_shout record_session as explained here:

https://github.com/MayamaTakeshi/shout_to_gsr

However, shoutcast protocol uses mp3 for data transfer so there is a performance penalty (mod_audio_fork sends the data as Linear16 which is the format used by the FS internally so there is no transcoding penalty).
