Thanks I am missing something there !
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 ? 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 !
