About OpenPhone
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.
