Sign Up
Create your Vobiz account at the registration page. You’ll get ₹25 in free credit to explore the platform.
Dashboard Overview
After signing in, you land on the main dashboard. Your API credentials - Auth ID and Auth Token - are displayed here. You’ll need these in every API request.
Buy a Phone Number
Go to the DID section and purchase a number. Filter by region to find numbers in the country you need. The number is assigned to an inbound trunk in the next step.
Create SIP Trunks
Outbound trunk (for placing calls)
In the Trunks sidebar section, click Create under Outbound Trunks. Give it a name, set the domain, then create a credential (username + password) for your platform to authenticate with.
Inbound trunk (for receiving calls)
Under Inbound Trunks, link the phone number you purchased to a destination URI. This is the SIP address where Vobiz sends incoming calls - usually your AI platform’s SIP URI.
Create an XML Application
In the Voice section, create an XML Application and set a webhook URL. Vobiz calls this URL when a call arrives, and your server responds with XML instructions. Then assign your phone number to the application.Use the interactive XML Builder to generate the XML your webhook should return without writing it by hand.
