Abstract
A wireless communication system including an originator media gateway to encode voice data into an IP packet depending on whether tandem free operation (TFO) or normal operation is being used. The media gateway makes such determination independent of the TFO protocol being used. In particular, the media gateway determines that TFO is being used by determining whether bits in particular fields of a predetermined number N of voice octets are filler bits or not. If they are filler bits, then TFO is being used, otherwise, normal operation is being used. If TFO is being used, the media gateway forms an IP packet with data from only another particular fields of the voice octets. If normal operation is used, the media gateway forms an IP packet with data from the entire voice octets. A target media gateway determines TFO or normal operation by examining the size of the received IP packet.
