Agents you build on Wixzel Voice place and answer phone calls over a SIP trunk you bring, and Vobiz is one of the carriers that works with it. Vobiz bills you for the trunk and the minutes at your own rates; the voice engine is billed per second of actual usage from your Wixzel Voice balance. This page covers where Vobiz keeps each setting. The steps that are the same for every carrier, and the troubleshooting list, are on SIP trunks.
Allowlist 95.216.218.102 for outbound calls, and send inbound calls to sip:95.216.218.102:5090. Every trunk returns both as platform_ip and origination_uri, so read them from GET /v1/sip-trunks rather than trusting this page to stay current.

​
How do I connect a Vobiz SIP trunk to Wixzel Voice?

Vobiz auto-generates a SIP domain per trunk in the form <trunkId>.sip.vobiz.ai: use that as your Wixzel Voice trunk’s host, not a bare IP.
1

Choose IP ACL or credentials

Vobiz supports both. For a platform-to-carrier interconnect the IP ACL is the one to use: add 95.216.218.102 to the trunk’s allowlist. Credentials go on your Wixzel Voice trunk’s username and password if you prefer digest authentication.
2

Configure the origination URIs

Vobiz uses origination URI for the opposite direction from Twilio: on Vobiz it is where calls leaving your trunk are routed, and it supports several with priority-based failover and weighted load balancing. Read their field descriptions rather than mapping the word across from another carrier’s console.
Vobiz expects the leading + on the number, so leave send_plus at its default.

​
What if a Vobiz call does not connect?

Work through When a call does not connect, and start with Vobiz’s own call logs: they show whether the call reached Vobiz at all and how Vobiz cleared it. In India, an account that has not finished KYC can have every outbound call cleared while holding a positive balance.

  • Quickstart: connect the trunk, register a number, create an agent and place a first call.
