I'm about to start offering VOIP for all of my existing customers.
My requirements are:
- callback modules must be available
- DID managment included


The only one I found is softswitch24.com, but don't really know how reliable they are.

Can I trust them? Any alternatives?

Have you ever provided VOIP service? Can you share any experience?
