Dear Folks, Thank you for useful responses. Please clarify one more query. In case, Both side(caller & callee) call is established and RTP(Both side iLBC) also flowing successfully but one side audio is coming and the other side audio is not coming. so what would be the problem(Other than mic bcoz mic is working properly)? Thanks & Regards, vijay
