Thanks Vinay But, I would be interested in knowing how TX_TYPE can be SPEECH_BAD or SID_BAD. It is mentioned in the same specification (6 TS 26.093 version 3.1.0 Release 1999 ( or the later version 4.1.)) that TX_TYPE can be SPEECH_BAD or SID_BAD. And that this can be the case with TFO and TrFO situations. But I could not get any information on how TX_TYPE can be SPEECH_BAD or SID_BAD. Also, in the RTP Payload format for AMR, when is it that the payload is severely damaged ? Could it be a result of some problem in the sampling process ? just a wild guess !!
