Bandwidth Global SIP Trunking review
A usage-based global SIP trunking service for enterprise PSTN, BYOC, and emergency routing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Bandwidth Global SIP Trunking provides all-IP voice connectivity for enterprises, UCaaS and CCaaS platforms, and organizations using SIP-enabled phone systems. Its scope covers global PSTN connectivity, usage-based SIP trunking, BYOC connectivity, number provisioning, porting, emergency calling, routing, failover, and self-service voice configuration. The service supports web, API, and self-hosted environments, making it a fit for communications teams that need to connect cloud or premises-based systems to public telephone networks.
The routing feature set is a central strength. Real-time routing can use IP, domain, phone-number, and SIP URI endpoints, while failover routes and weighted endpoint distribution support more controlled traffic handling. Bandwidth also provides SBC integration guides for AudioCodes, Cisco CUBE, Ribbon, and Oracle. TLS-encrypted SIP signaling is available as an option, and the platform includes capabilities for 911, 112, and emergency routing. Number provisioning and no-interruption porting extend the service beyond basic trunk connectivity, particularly for organizations moving existing voice numbers into a broader communications environment.
Pricing is usage-based or volume-based, with full product pricing available on request according to the vendor’s pricing page. That model may suit enterprises whose requirements vary by traffic, geography, and deployment, but it gives buyers no fixed entry price for initial comparison. Bandwidth offers a free Build trial, although it is not a perpetual free plan. Organizations seeking global PSTN access, BYOC connectivity, flexible routing, and integrations with established SBC platforms should consider it. Teams looking for a simple, fixed-price trunking package or an ongoing free tier should look elsewhere.
