Communication
Bandwidth
Bandwidth provides cloud-based voice, messaging, and 911 APIs that enterprises use to embed communications into their applications.
What is Bandwidth?
Bandwidth sits a layer below most of the communications platforms that businesses interact with daily. While companies like Zoom, RingCentral, and Microsoft Teams present polished consumer-facing interfaces, many of them depend on Bandwidth's carrier-grade API infrastructure underneath for PSTN access, phone number provisioning, and SMS delivery. Founded in 1999 in North Carolina, Bandwidth built its own nationwide network infrastructure rather than reselling capacity from other carriers, which gives it unusual control over voice quality and regulatory compliance in the US market.
The platform exposes RESTful APIs for voice calls, SMS and MMS messaging, 911 access, and toll-free number management, all backed by Bandwidth's direct carrier connections rather than third-party aggregators. Enterprise customers use the APIs to build custom communications workflows, while software vendors integrate Bandwidth as the telecom layer inside their own products. That wholesale positioning means a Bandwidth infrastructure event can cascade to multiple downstream platforms simultaneously, affecting the end users of those platforms without those users ever knowing Bandwidth is involved.
Because Bandwidth is infrastructure rather than a finished product, its outage symptoms appear at the API layer first. SIP interconnect failures cause voice calls to fail at the carrier handoff point — callers hear fast-busy tones or errors before ringing begins. SMS delivery stalls in a queued state, with messages not reaching recipients even after successful API acceptance. Phone number provisioning requests return errors or hang indefinitely. 911 call routing failures — a safety-critical function — trigger immediate escalation procedures when detected. Downstream platforms using Bandwidth report call quality degradation or complete telephony failure to their own customers without necessarily surfacing Bandwidth as the root cause.
Outage.gg tracks Bandwidth platform status using real-time community reports from developers and businesses using Bandwidth's voice, SMS, and number management APIs. If calls are failing, messages are not delivering, or provisioning is stuck, the live status page shows current impact.
