Start at Simulation SIP setup.
Dograh does not speak SIP itself, its SIP provider Cloudonix does that on Dograh’s behalf. So the address you give Tuner belongs to Cloudonix, and the steps below set up a route through it to one specific agent. You don’t need your own SIP carrier or a phone number, simulations run over the Cloudonix domain Dograh already provisions for your organization.

​
Before you start

  • The Tuner node configured and enabled on your Dograh workflow (see Connecting to Dograh).
  • In Tuner, that same agent has Call Direction set to Inbound.
  • The agent already works, tested from the Dograh agent editor.
An inbound simulation only attaches to its scenario when the Tuner agent’s Call Direction is Inbound. If it’s set to Outbound, Tuner matches the returned call on a different field and files it as ordinary production traffic instead.

​
Step 1: Add an extension for simulations

In Dograh, open Telephony configurations → Dograh Cloudonix SIP. Under Phone numbers, click Add phone number and enter a short extension, for example 9001. You don’t need a real phone number, that field also accepts plain extensions. Dograh registers it with Cloudonix for you.

​
Step 2: Point the extension at your agent

Edit the extension you just added, set its Inbound workflow to the agent that should answer simulation calls, and save.

​
Step 3: Publish the workflow

In the workflow editor, click Save, then Publish.
Inbound calls always run the published version of a workflow, never the draft. If the Tuner node is only in your draft, calls will connect and the conversation happens normally, but nothing reaches Tuner and no error appears anywhere.

​
Step 4: Build the SIP URI

Expand SIP connectivity on the Dograh configuration page, choose your region, and copy the inbound hostname. Combine it with the extension from Step 1:
Set the region before copying anything, every value on the panel is region-specific, including the port:
On India or UAE, leaving the port off sends the call to port 5060, where nothing is listening, the failure looks like an unreachable agent rather than a wrong address. Add :9060 or :9081 to the URI.

​
Step 5: Paste into Tuner

  1. Agent Settings → SIP Settings.
  2. SIP URI: the address you built in Step 4.
  3. Leave Username and Password empty, Dograh’s inbound endpoint does not use SIP authentication.
  4. Click Verify & Save. Tuner places a short test call immediately.
SIP configuration in Tuner
Known issue. With both auth fields blank, verification can fail with “endpoint did not answer.” Entering any non-empty placeholder values, for example tuner and tuner, works around it, Dograh never checks them. Clear both fields again once this is fixed.

​
How calls are matched to scenarios

Nothing to configure, this is automatic. Cloudonix reports the caller’s SIP call ID to Dograh, and Dograh includes it when it exports the finished call. Tuner uses that ID to attach the call to the scenario that placed it. Without it, the call would still be ingested, just filed as ordinary production traffic instead of a simulation result.

​
Troubleshooting

Paste your SIP URI into Agent Settings → SIP Settings, click Verify & Save, and you’re ready to run simulations.
