There are some open source modules that do something similar*, including this one I wrote:
https://github.com/drachtio/drachtio-freeswitch-modules/tree/master/modules/mod_audio_fork

*by “similar” I mean it does not duplicate the RTP stream, headers and all, but rather sends the voice stream in linear16 format to a far-end websocket server that you provide.

Dear All ,
i am a newbie just started trying and learning Freeswitch platform. Until now my area of focus was call recording for various telephony platforms like Avaya, cisco , and many more.. i would like to know if there is any API available in Freeswitch platform for recording call by a third party application , by streaming the voice as a duplicate RTP stream to the IP of Call Recording application . what I understood that there is Call Recording API like session recordFile available in the ESL for recording the calls in the system itself. But i couldnt find an option to record from a 3rd party application by getting the duplicate RTP stream. please let me know if any information is available on this query.

Thanks and regards

Hello Dave,                   Thanks a lot for the information.  This was exactly what I was looking for.  i hope that , the freeswitch will not be loaded too much when more number of concurrent calls are getting streamed using mod_audio_fork through a websocket.  on the other hand , In the normal recording option available with Freeswitch , there is a high chance that the Media processing for recording is taking lot of system resources and will limit the number of concurrent calls.   Thanks again for the valuable information you shared with me. 


Thanks and regards
Rasheed
