I was wondering if I could get peoples opinion on the below.

I am based in the UK with a Cirpack and Clarent softswitchs and providing VoIP solutions to the commercial and residential market. We use ATAs at customer premises to connect to us. Would asterix be a possible solution here instead of using the above vendors or is asterix more of a PBX that can be installed in customer premises and connect back to our softswitch?

Thanking you.
