Bring Your Own Carrier (BYOC)
With Voxbi, you stay in control of your voice infrastructure. Our Cloud PBX platform supports BYOC—Bring Your Own Carrier—allowing you to connect the SIP trunk provider of your choice directly to our phone system. Whether you're migrating from an existing setup or working with multiple carriers across locations, Voxbi adapts to your needs without locking you into a single voice provider.
Why BYOC matters for enterprises and multi-site businesses
Carrier independence is more than just flexibility—it’s strategic. In enterprise and multinational environments, businesses often have existing agreements with local carriers, or operate across regions where different providers are better suited. Our Bring Your Own Cariier feature allows you to maintain those relationships, while benefiting from the powerful features of Voxbi’s Cloud PBX.
It's also critical in scenarios where redundancy, failover, or regulatory compliance is required. BYOC lets you:
- Route calls through multiple carriers for high availability
- Isolate services by region or business unit
- Maintain control over number ownership and porting
- Maintain numbers in countries where number portability is not possible
- Leverage local telephony for better pricing or regulatory needs
Certified and compatible SIP trunk providers
The following list includes SIP trunk providers that have been either certified by Mixvoip or are widely used and confirmed to be compatible with the Voxbi Cloud PBX. Being certified means the provider has been fully tested by our engineering team for long-term reliability and feature support. Compatible providers have been successfully deployed by our customers without issues. While only a selection is listed, Voxbi is fully SIP-compliant—any standards-based SIP provider can be integrated. Thanks to our deep experience in SIP signaling and header manipulation, even complex or non-standard implementations can be supported.
Still using ISDN, analog lines, or PRI?
No problem. If you're working with legacy carriers or infrastructure, Mixvoip can supply and configure VoIP gateways to integrate analog, ISDN, or PRI/E1 lines directly into the Voxbi PBX. This allows you to preserve existing services while modernizing your communication platform.
