Hi, I'm having the next problem: When using record_session on long calls (more than 20 minutes) at some point the final output file "bad mix" the channels, so the A-Leg and B-Leg get one over the other in different times. It looks that in some point the A-Leg "cuts" or "accelerate" audio frames and as result the final audio sounds like two people talking at different times or at the same time but whitout order. Like: During Call Audio: 1. A: Hi Bro 2. B; Hi Man, How are you?? 3. A: Excellent Bro 4. B: Good For you 5. A: Have a nice Day 6. B; Same to you On Final Output Audio File: 1. A: Hi / B: Hi man How are you?? 2. A: Bro 3. B: Good For you 4. B: Same to you / A; Excellent 5. A: Bro 6. A: Have a Nice Day Tried to use same codec on both legs but not working, the result for long calls is the same. also tried to change the .wav for a .gsm but when converting, the result is the same.
