As I stated previously.

I would look into the Sylantro Feature switch.

They would be able to give you more opened opions on which carrier class Voice switch works the best.

You could always go with a nortel VOIP Class 5 switch or a Avaya VOIP Class 5 switch ( I believe it is the 7ESS. Not postive though).

I have seen the Sonus switch with Sylantro feature switch but had isssues due to the way the company I worked for deployed it.
