ahh..american arrogance. I assumed you were in the US. We pay $2000 a month for DS3/SS7 to national carrier. We will soon be dropping the SS7 and turning that voice DS3 into a bandwidth DS3. We will still use the carrier but all calls will terminate to them VoIP. It will save us over $2000 a month.

For us to take EuroISDN off them, with the same features as SS7, we have to be put through a protocol converter, now this isn't an issue for us, but it is for them. Most UK phone companies (i.e. BT or the smaller regional carriers) all use SS7, everywhere! For the most part they don't accept VoIP termination (although I think BT might have some facilities for this). So they very much try and push SS7 on interconnects. And that's why SS7, for me (and I think for quite a few others taking PRI style links in the UK) is so important.

Everything else goes out VoIP via SIP to national carriers and they terminate it. Can't you use a channel bank or an FX card to connect to PSTN?
