Greetings- I've recently been looking at TCAP services from both my A-link provider and another, very large, company. The proposal from the very large company came back with relatively good rates as compared with the incumbent A-link provider. However (there's always one), their proposal is predicated on my using TCAP over VPN. I've never heard of TCAP over VPN, and my signaling gateway/controller vendor says they haven't either. So I'm looking for whatever information I can find. My purpose for asking here is that I'm wondering if this is possible with Asterisk, and if I can use Asterisk with lib-ss7 or similar to create a translation device from which I could translate TCAP over VPN to legacy TCAP on A-links for connection to my switch. Thanks- Joe
