The People Who Built the Phone Switch Want to Run the Conversation
FreeSWITCH helped teach the internet to make phone calls. SignalWire is trying to teach those calls what to do next - and to keep the AI close enough to hear the answer.
The Call Center That Started Listening
Ozonetel began by moving business calls to the cloud. Its more interesting bet is that the conversations themselves can tell a company what to fix next.
tyntec turns the humble message into serious business
A WhatsApp conversation can sell a jacket. A network signal can help verify a customer. Tyntec has spent two decades connecting those everyday moments to the machinery of mobile telecoms.
Bandwidth Built the Phone Network Your Software Forgot It Needed
Most communications software companies rent the road. Bandwidth spent decades laying its own - then turned that network into APIs for Google, Microsoft, Zoom and the coming wave of voice AI.
IntelePeer Spent 23 Years Plumbing the Phone Network. Then It Gave Its AI Business a New Name.

Bird
The Dutch company that rebuilt telecom's plumbing now carries a claimed 40% of the world's commercial messages - and spent two years trying to delete Twilio's margins with a 90% price cut. Bird's next bet is that the software placing those calls will be an AI agent, not a marketer.
