Publication number: 20070230448Abstract: Embodiments of the present invention provide a method and a media gateway for realizing a packet-packet model session. According to an embodiment of the present invention, the media gateway determines whether the session meets the TrFO protocol. In the case that the session doesn't meet the TrFO protocol, the media gateway inserts a pair of back-to-back TCs, activates the pair of back-to-back TCs such that the pair of back-to-back TCs perform the TFO negotiation, thus making the pair of back-to-back TCs work in a pass-through mode. In the embodiments of the present invention, because it is possible to bypass the codec ability of the pair of back-to-back TCs, the voice quality deterioration introduced in the prior art due to adopting the codec conversion may be avoided.Type: ApplicationFiled: March 29, 2007Publication date: October 4, 2007Applicant: Huawei Technologies Co., Ltd.Inventor: Dahai Wang
