> 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- 

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.
