What is Bandwidth?
Bandwidth adds branded calling — the first move beyond closing self-service gaps.
Most of Bandwidth's recent changelog reads as friction removal: Voice API debug logs surfaced in Voice Insights so customers stop opening tickets, self-service FOC date changes on port-in orders, MOS scores in the app, a longer delivery-receipt window. Identity Presentation breaks that pattern — it is a new product surface rather than a gap closed, putting brand name, logo and call reason on the recipient's handset with a pre-call authentication API to stop the display being spoofed.
What is 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.

Bandwidth
6.3COMMS
Bandwidth adds branded calling — the first move beyond closing self-service gaps.
◆ Current state
Most of Bandwidth's recent changelog reads as friction removal: Voice API debug logs surfaced in Voice Insights so customers stop opening tickets, self-service FOC date changes on port-in orders, MOS scores in the app, a longer delivery-receipt window. Identity Presentation breaks that pattern — it is a new product surface rather than a gap closed, putting brand name, logo and call reason on the recipient's handset with a pre-call authentication API to stop the display being spoofed.
◆ Where it's heading
Two tracks. Coverage keeps expanding country by country toward full PSTN replacement — Brazil, Mexico and South Korea landed together — which is the wholesale carrier business growing its footprint. The newer track is moving up the stack into call identity and trust, where the product is not minutes but whether the call gets answered. Identity Presentation arriving as a beta built on third-party providers suggests Bandwidth is assembling that layer rather than building it outright.
◆ Prediction
Expect Identity Presentation to move from beta to general availability with a defined pricing model, and the Identity Authentication API to be positioned alongside it as the anti-spoofing control. Country coverage announcements should continue on their steady cadence.
OpenPhone
0.0COMMS
OpenPhone turns Sona into a deployable front-line AI agent with transfers and per-scenario instructions.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
