Remenber sigtran is a very cost effcient evolution of traditional links SS7, more and more telco's STP today handle sigtran signaling, and I think is more cheap cards ethernet than cards E1's.<br><br>Thanks and regards.<br><br>--- El <b>jue, 14/8/08, asterisk-ss7-request@lists.digium.com <i><asterisk-ss7-request@lists.digium.com></i></b> escribió:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;">De: asterisk-ss7-request@lists.digium.com <asterisk-ss7-request@lists.digium.com><br>Asunto: asterisk-ss7 Digest, Vol 42, Issue 14<br>Para: asterisk-ss7@lists.digium.com<br>Fecha: jueves, 14 agosto, 2008 2:00<br><br><pre>Send asterisk-ss7 mailing list submissions to<br>
