[Freeswitch-users] Feature Comfort Noise to select different codecs on both legs of a Call

Hello Everyone, This is Something New. I am using Freeswitch 1.5 version. I am trying to add comfort noise in media by bridge_generate_comfort_noise variable. But It is choosing same codec for both legs of a call, Instead I want it to select different codecs for both A leg and B leg. In some situation , I need to have 8000 bps on leg A and 16000 bps on leg B, But bridge_generate_comfort_noise by default selects same codec on both leg. How do I select different codecs for comfort noise on both legs ? Please Help in this regard. Thanks. Ajinkya
