Hi,<div><br></div><div>You should try using "sox" if there is nothing you've found in freeswitch. Execute a system sox command and input the two recordings. Later the mixed audio can be played back to user.</div>
<div> </div><div>Another approach can be to use a conference bridge in which a local channel and the incoming caller are bridged and the conference is recorded. The recorded conference can be played back or used as well.</div>
