OpenPhone turns Sona into a deployable front-line AI agent with transfers and per-scenario instructions.
OpenPhone is hardening Sona, its AI phone agent, into something businesses can actually put in front of customers. Sona can now route calls to the right teammate when a human is needed, and admins can give it custom instructions per scenario (lead qualification, cancellations, booking) with templates to start from. Around it, the call flow builder keeps maturing: multiple routing setups with quick switching, in-place inbox switching during flow construction, and a Go-to Step primitive for cleaner branches.
Twilio's voice AI stops cutting callers off mid-sentence, using its own turn-taking model.
Twilio shipped a dense batch on November 11 to 13. Smart Turn Detection for Conversation Relay is now generally available: an in-house model judges from meaning, not silence, when a caller has finished speaking. Alongside it come US Branded Calling across T-Mobile, Verizon and AT&T from one registration and Apple Business Invitations, both in private beta, plus Email Logs filters and search and more specific A2P 10DLC rejection codes from December 9.

The core bet is an AI-handles-first-contact, humans-handle-edge-cases pattern. Each Sona release is closing a deployment-blocker (instructions, transfers, free trial), while the call-flow tooling underneath is getting more flexible so AI and human routing can coexist in one config. Plan-tier expansion (call hold on Starter) suggests OpenPhone is also chasing volume in the lower segment.
Expect Sona to gain CRM-aware context (caller history, deal state) and outbound use cases — proactive callbacks, scheduled follow-ups. Pricing for Sona usage is likely to evolve from a flat add-on toward usage- or outcome-based once volume appears.

Two threads run in parallel: trust and identity at the carrier and channel level (branded calling, Apple invitations, 10DLC feedback, STIR/SHAKEN status) and a voice AI stack where Twilio now ships its own models instead of only relaying third-party ones. Email keeps getting operator tooling around deliverability.
Expect more of Conversation Relay to move to Twilio-built models and settings, and the branded calling and Apple invitation betas to widen in the coming months, as earlier private betas here have.
