Your questions about toll-free voice answered

They’re business phone numbers customers can call for free. You can port or provision numbers in 70+ countries, connect through SIP or Voice APIs, and route calls over Sinch’s owned, redundant Tier-1 network for consistent quality.

Our global network is built on direct, Tier-1 carrier relationships, minimizing handoffs to reduce latency and jitter. Automated failover and redundant systems keep calls crystal clear.

Yes. Our dedicated, global porting team has decades of experience managing complex, multi-carrier projects for large enterprises with zero downtime.

The pay-as-you-go model removes expensive, fixed-capacity PRIs and multi-carrier contracts. You only pay for what you use, cutting overall telecom spending.

Unlike many resellers, Sinch owns and operates its core global voice network, including a Feature Group D design for toll-free. Our patent-pending Rapid Recovery technology adds automated failover for maximum uptime.

They work together, but they’re not the same. A toll-free number is what customers dial for free; VoIP is the technology that carries the call over the internet on Sinch’s robust global network.

Voice is available in over 70 countries, while combined voice and SMS/MMS is primarily supported in the U.S. and Canada. For other regions, use additional number products for messaging.

You can connect to our global network by porting existing numbers or provisioning new ones. Then set up your call logic with APIs or tools and deliver great experiences over our owned, redundant Tier-1 network. 

To get started, you’ll need a Sinch Enterprise Account and compatible IP-based infrastructure (such as an IP-PBX or contact center platform).

Proactive monitoring catches and blocks suspicious activity, helping protect budgets. We also support STIR/SHAKEN in the U.S. to combat spoofing.
