<div>Thanks</div>

<div>I am missing something there ! </div>
<div> </div>
<div>Sigtran has signalling over IP and media over TDM - then, you still need a TDM card for your voice - so you still need these expensive SS7 cards - or are there TDM cards that are not SS7, and cheaper ?</div>
<div> </div>
<div>Initially, I thought that Sigtran was full ip, which is wrong, but that appealed me as a way to avoid the ss7 cards - just one redundant NIC, and as you say, unlimited traffic - but I see we still need them ! I am lost</div>

<div>Hi</div>
<div> </div>
<div>That is what I understood and I fail to see the interest of having the voice on one media (tdm) and signalling over IP - is it just to have one more TDM channel ? what's the benefit here ?</div>
