> > This is assuming that you only want to do signalling. No voice etc. The only thing SS7 does is signaling, Obviously you'll need enough bearer channels to handle your voice traffic which occur on a completely different trunk group. A single 56kbps SS7 A-link can easily handle thousands of call creations per second. The Digium SS7 stack I was referring to was LIBISUP http://www.voip- info.org/wiki/index.php?page=Asterisk+ss7+LIBISUP I haven't used it in the real world, All of my SS7 with Verizon is handled by a Tekelec t7000 switch. You may also want to look at Verisign, They can provide SS7 links with national (USA) coverage and they have a product calls SIP-7 which is their SS7 talking to your SIP server. http://www.verisign.com/products-services/communications-services/ connectivity-and-interoperability-services/SIP-7_Service/index.html -Matt -- Matthew S.
