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 Dendrite?

A forked, relicensed Dendrite spent its first year catching up on Matrix protocol and security debt

The window opens with the first release after forking from matrix-org/dendrite under AGPLv3, which fixed long-standing state-reset bugs and added I2P and Onion listening. What follows is a security release closing a server-side request forgery vulnerability, then a release adding room version 12 support and two MSC implementations, and finally two quick patches for unresponsiveness, v12 room joins and malformed PDUs blocking whole transactions.

Bandwidth vs Dendrite: editorial side-by-side

B6.3

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.

D0.0

A forked, relicensed Dendrite spent its first year catching up on Matrix protocol and security debt

◆ Current state

The window opens with the first release after forking from matrix-org/dendrite under AGPLv3, which fixed long-standing state-reset bugs and added I2P and Onion listening. What follows is a security release closing a server-side request forgery vulnerability, then a release adding room version 12 support and two MSC implementations, and finally two quick patches for unresponsiveness, v12 room joins and malformed PDUs blocking whole transactions.

◆ Where it's heading

This is a fork proving it can carry a homeserver. The order is telling: license and state correctness first, then a CVE, then protocol currency with room version 12, then the operational bugs that surface once people actually run it. Several fixes carry outside contributor credits, which is the fork's clearest sign of life.

◆ Prediction

Expect continued protocol catch-up on newer MSCs and room versions plus operational fixes, since federation compatibility is the constraint that sets this project's agenda.
