AVOXI Global SIP Trunking review
A global SIP trunking service for businesses connecting PBX, UCaaS, and contact centers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AVOXI Global SIP Trunking connects existing PBX, CCaaS, and UCaaS systems to AVOXI’s international voice network. It supports inbound SIP origination, outbound SIP termination, international calling, local caller ID and CNAM, and provisioning for local, toll-free, non-geographic, and mobile numbers. The service is aimed at organizations managing international business voice, distributed communications, or contact-center operations. It is available through web-based provisioning and VoIP API access, with coverage across more than 160 countries.
The published SIP Trunk plan includes unlimited channels stated on the product page, while outbound calls are charged per minute. AVOXI describes recurring trunk charges alongside usage-based outbound calling fees, and there is no free plan. This contact-sales pricing model may suit organizations that need international voice coverage and can evaluate costs based on calling patterns, but it gives buyers less immediate pricing visibility than a self-serve provider. Organizations should also account for outbound usage when comparing total voice costs.
Platform fit is a central strength. AVOXI lists integrations with Microsoft Teams, Five9, Genesys, Zoom, Amazon Connect, Salesforce, HubSpot, and Zendesk, alongside broader PBX, CCaaS, and UCaaS integration. Routing and analytics support operational oversight, while fraud monitoring and TLS and SRTP encryption options address important voice-management and security needs. Businesses seeking global number provisioning, API access, and contact-center connectivity should consider AVOXI. It is less suitable for buyers who prioritize transparent self-serve pricing, a free plan, or a voice service without per-minute outbound charges.
