A Campaign Agent is a reusable bundle of webhook configuration — the Answer URL, the Hangup URL, and any static SIP headers — that one or more campaigns share. Create the agent once and you can launch a hundred campaigns against it without re‑typing those URLs.Documentation Index

URL
The Agents list

| Section | What it contains |
|---|---|
| Header | Friendly name (e.g. API Test Agent 2) and the creation date. |
| Answer | The URL Vobiz POSTs (or GETs) when a campaign call connects — your server’s IVR / AI flow lives here. |
| Hangup | Where Vobiz POSTs the final call result. Shown as Not configured if you skipped it. |
| Static SIP Headers | Custom headers Vobiz attaches to every campaign call placed through this agent (none by default). |
Create a new Agent
Click + New Agent in the top‑right.
| Field | Required | Notes |
|---|---|---|
| Name | ✅ | Something descriptive — “Appointment Reminder Agent”, “Q4 Survey Bot”. You’ll pick this from a dropdown when creating campaigns. |
| Answer URL | ✅ | Method (POST recommended) + URL. Vobiz hits this when a campaign call is answered. Same XML conventions as a normal XML application. |
| Hangup URL | – | Optional. Vobiz POSTs the call result here when the call ends. Recommended in production — most analytics depend on it. |
| Static SIP Headers | – | Click + Add header to attach key/value pairs that Vobiz sends with every outgoing INVITE. Use for tagging traffic (X-Campaign-Source: q4-reminders) or routing hints. |
Static SIP Headers — when to use them
The headers you add here are attached to every INVITE Vobiz sends on behalf of campaigns that use this agent. Common patterns:X-Campaign-Source— tag for your downstream PBX or CRM to know the source.P-Asserted-Identity— carrier‑specific identity routing (check with your trunk provider first).X-RingTime— pass a max ring time hint to the receiving system.
