description The present invention is directed to methods, apparatus and systems for optimizing media paths in communications networks. An exemplary embodiment includes the steps of a first SBC (SBC1) receiving a session request including a SDP offer for a session between first and second devices including media stream(s), said request being sent by a second SBC (SBC2) and traversing a portion of a signaling path including intermediary device(s), determining that media stream(s) should bypass one or more of the intermediary device(s), generating and transmitting to SBC2 from SBC1 a SDP answer including at least one of: (i) all SDP media descriptor transport addresses being set to zero; (ii) all SDP media stream connection values being set to 0.0.0.0 and at least one media transport address being non-zero; or (iii) header information or SDP information indicating that at least one intermediary device should be bypassed for the one or more media streams.
