Frequently asked questions about Sinch Voice

A voice platform is a cloud-based suite of tools that lets businesses manage all their voice communications. The Sinch platform provides the foundational network connectivity, programmable APIs, and security services needed to make, receive, and control calls at scale, without managing complex telecom infrastructure.

Sinch connects easily with your current setup. You can use Elastic SIP Trunking to connect your on-premises PBX to our global cloud network, or use our Bring Your Own Carrier (BYOC) solution to power platforms like Microsoft Teams and Webex Calling with our network.

SIP Trunking connects your existing phone system (like a PBX) to the public telephone network over the internet, replacing traditional phone lines. A Voice API lets you build new, custom voice experiences—like automated IVRs, call tracking, and in-app calling—directly into your own apps and software.

Sinch uses a multi-layered approach to keep your calls safe. We’re fully compliant with STIR/SHAKEN to verify caller IDs and combat spoofing, use proactive fraud detection to monitor and block suspicious traffic, and offer services like CNAM Caller ID to make sure your verified name shows up when you call.
