IP Audio hairpinning

h5n1,
easy. there are two buzzwords related to voip: shuffling and hairpinning. shuffling is a process of establishing rtp voice stream directly between endpoints (ip phones), bypassing medpro board completely. call control is still done via c-lan, however. hairpinning is somewhat similar, it's a process of switching rtp voice packets through medpro but without using tdm bus. i.e. in this case, medpro board acts like proxy. rtp path from both enpoints goes to medpro but the board itself doesn't allocate tdm bus for this conversation and doesn't use precious tdm timeslots, it just switches rtp packets back and forth.
