Why customers make the Sinch^® switch

Yes, Bandwidth has deployed its own CLEC network. Bandwidth’s owned nationwide all-IP network is supported by our 24/7 NOC for US network monitoring. We have a strong reputation for reliability, secure redundancy, and uptime.

Most CPaaS providers are software companies that buy access to someone else’s network. Sinch is a step closer. They own their network infrastructure, but through the acquisition of wholesale transit businesses. This means their network was built for carriers first, rather than enterprises. Bandwidth’s identity and business model was built as a carrier from the start: owning numbers, originating and terminating traffic on its own infrastructure. The infrastructure, the routing logic, the support model: Bandwidth’s network was built around our customers from the start. When something breaks, there’s no upstream carrier to blame. That accountability is a foundational principle that shapes how our network was built and who it’s built to serve.

For most teams, it’s an endpoint swap, not a rebuild. Your application logic stays where it is. You repoint your endpoints to Bandwidth’s HTTPS APIs rather than rewriting your call flows from scratch. Migration cost is the real reason teams stay locked into a provider, so Bandwidth Build gives you a sandbox and dev credits to test before you commit. The honest caveat: teams without developer resources to reconfigure and retest call flows should plan for engineering time. Talk to a Bandwidth expert to scope your specific migration.

Yes. Bandwidth’s Voice API streams live call audio bidirectionally over WebSocket, so you can connect calls to AI tools like OpenAI, Deepgram, or LiveKit in real time. There’s no record-then-process delay. Your AI agent listens and responds live, handles natural interruptions, and hands off to a human when needed. The combination of SIP URI Ingress and SIP REFER also lets an AI agent exit a call flow cleanly, routing to a SIP address and transferring out without staying on the hook for both call legs. These are deployment patterns that phone-number-only routing can’t support.

Yes, and it’s a native capability, not a separate product. Voice WebRTC lets you embed browser- and app-based calling on the same owned network, with a single SKU covering both inbound and outbound at a flat $0.004/min. Connections are DTLS/SRTP encrypted by default, because the protocol can’t establish an unencrypted connection. One difference to weigh against Sinch: Bandwidth’s Voice WebRTC is voice-only. If your use case needs video in the same product, Sinch offers that today and Bandwidth does not.

For US, Canada, and EU-centered deployments, Bandwidth’s owned network outperforms, which is why enterprises like Google, Genesys, and Pennymac choose it for the reliability and control that a direct-to-carrier network delivers across 65+ countries. Sinch has a dedicated APAC presence and more transcription language support. However, Bandwidth’s advantage is the Universal Platform, which gives customers with multinational operations a single login and unified architecture, instead of a network that’s been stitched together with acquisitions.

Bandwidth provides award-winning support with a 95%+ CSAT rating, and phone support is included in every plan rather than sold as a paid add-on. Voice AI and quality issues need engineer-level help, not a generalist reading from a script, so Bandwidth backs customers with a named support model and multi-channel access instead of multi-day ticket queues. Support quality is one of the most consistently cited reasons customers choose Bandwidth in competitive evaluations, especially during onboarding and technical escalations.

Yes. Bandwidth offers free Signature Support and hands-on expertise for messaging registration, and it particularly excels at helping customers stand up their 10DLC messaging. Registration is often the slowest, most confusing step in launching a messaging program, so Bandwidth guides you through it rather than leaving you to decode compliance requirements alone. You get expert help getting registered correctly and messaging sooner, at no extra cost.

Bandwidth delivers Voice and Messaging on one owned and operated platform, and its messaging registration support is a real strength, particularly for 10DLC. Here’s the honest tradeoff to weigh. If your priority is programmable Voice, voice AI infrastructure, and 10DLC messaging in North America, Bandwidth is a strong single-vendor fit. If you need global A2P messaging across many channels, such as voice plus WhatsApp plus SMS worldwide, Sinch’s multi-channel messaging breadth may cover more of that today. Match the choice to where your volume and roadmap actually are.
