I'm running my company's phone system on a cloud-hosted Asterisk system -- it's basically the same thing that we've been using for years, and works quite well, though we're still tied to physical desk phones.
Curious if anyone has good resources for working with an Asterisk core for an app like this. I recall seeing a Rails framework for Asterisk out there somewhere, but no clue if it's any good. Would love to hear thoughts...
