Hello, I have a specific requirement that I need to record both the incoming and outgoing audio in a set of files with a time granularity i.e. suppose after each 1 min the outgoing audio should be stored in out_XXX.wav and the incoming audio to be stored in in_XXX.wav I did previously performed file recording using --rec-file option with pjsua application and then using cc to connect the audio port to the file registered port after the call gets connected. But now I need to automate the process with a certain granularity as stated before. Do I need to insert any code into the pjsua_app.c file and if so at which place/function to insert? I will be very helpful if someone can give some hints so that I can achieve my requirement! Thanks!
