It has three parts: * **Part A — 60db side:** complete KYC, set up trunks, rent a number, and collect the values QCall needs. * **Part B — QCall side:** add the SIP Dialer in the QCall dashboard. * **Part C — 60db side:** point inbound calls back to QCall. > **You need one thing from each side.** 60db gives you a *SIP domain + username + password + phone > number*. QCall gives you back a *SIP URI* that 60db must forward inbound calls to. That > two-way handshake is the whole integration. *** ## How it works (architecture) ``` ┌─────────────────────────────────────────────┐ │ QCall │ │ (SIP trunks + AI agent backend) │ └─────────────────────────────────────────────┘ OUTBOUND ─────────────────────────────► AI agent dials a lead: Outbound Trunk QCall → 60db SIP domain (termination) ─────► sends INVITE to authenticated with username/password your 60db SIP domain ──► PSTN ──► Lead's phone INBOUND ◄───────────────────────────── Caller dials your 60db number ──► 60db ──► routes (inbound trunk) to your QCall SIP URI ────────────────► Inbound Trunk (matches the number) ──► Dispatch Rule ──► AI agent answers ``` * **Outbound = QCall → 60db.** From QCall's point of view, 60db is where the call *terminates* into the phone network. That is why QCall calls it the **SIP Termination URI**. * **Inbound = 60db → QCall.** 60db's inbound trunk must forward incoming calls to QCall's SIP address. *** ## Before you start | Requirement | Where (60db Dashboard) | Why | | - | - | - | | **KYC approved** | **Dialer → KYC** | Needed to buy numbers. PAN + Aadhaar/passport + address proof. | | **Trunk set up** | **Dialer → Trunks** | Needed for calls, recordings and caller ID. | | **Wallet balance** | Billing / Wallet | Number rental is charged at purchase. | > KYC can only be submitted in the dashboard, not through the API. Review states are > `DIALER_KYC_PENDING`, `DIALER_KYC_APPROVED` and `DIALER_KYC_REJECTED` (resubmit with correct documents). *** ## Credential cheat-sheet (60db → QCall field mapping) Fill this in as you go through Part A. You'll paste the right-hand column into the QCall dashboard in Part B. | What you get from 60db | Example value | QCall dashboard field | | - | - | - | | Outbound trunk **SIP domain / host** | `` | **SIP Termination URI** | | Trunk **SIP credential username** | `qcall_prod` | **SIP Username** | | Trunk **SIP credential password** | `••••••••••••` | **SIP Password** | | Rented **phone number** | `+919876543210` | **Phone Number** | | *(any label you like)* | `My 60db Line` | **Dialer Name** | Then, after saving in QCall, you receive **one** value to bring *back* to 60db: | What QCall gives you | Example value | Where it goes in 60db | | - | - | - | | Your **SIP URI** | `3.109.230.240:5060` | Inbound trunk **destination / forward URI** | *** # Part A — 60db: get your SIP credentials & number ## Step 1 — Create your 60db account 1. Sign up / log in at **[https://app.60db.ai](https://app.60db.ai)**. 2. Select the workspace you want to use. Numbers, trunks and billing are **per workspace**. 3. Top up your wallet. Buying a number with a low balance fails with `402 RECHARGE_REQUIRED`. ## Step 2 — Complete KYC (Gate K) 1. Go to **Dialer → KYC**. 2. Upload **PAN**, **Aadhaar or passport**, and **address proof**. 3. Wait for the status to become **Approved**. You can't buy numbers until then. ## Step 3 — Set up the SIP trunk (Gate T) 1. Go to **Dialer → Trunks**. 2. Set up the **outbound trunk** (for placing calls) and the **inbound trunk** (for receiving calls). 3. **Download / copy your SIP credentials**: SIP domain (host), username and password. * SIP domain → **SIP Termination URI** in QCall * Username + password → **SIP Username** and **SIP Password** in QCall 4. Keep the password safe. If you lose it, regenerate the credentials and update the QCall dialer. > Until a trunk exists, 60db call endpoints return `409 DIALER_NOT_PROVISIONED`. ## Step 4 — Rent a phone number 1. In **Dialer → Numbers**, search the shared pool and buy a number (API: `GET /dialer/pool` → `POST /dialer/pool/allocate`). 2. Write it down in **E.164 format with `+91`**, e.g. `+919876543210`. → This becomes the **Phone Number** field in QCall. 3. Set it as the **default caller ID** (API: `PUT /dialer/caller-id`) so outbound calls show this number. ✅ **At this point you should have all four values** for the cheat-sheet: SIP domain, username, password, and phone number. *** # Part B — QCall dashboard: add the SIP Dialer 1. Log in to the **QCall dashboard**. 2. Go to **Settings → Dialers** (the "Dialers" / "Phone Numbers" area). 3. Click **➕ Add Dialer** and choose **SIP** as the dialer type. 4. Fill in the form using your cheat-sheet: | Field | What to enter | | - | - | | **Dialer Name** | Any label, e.g. `My 60db Line` | | **Phone Number** | Your 60db number in E.164, e.g. `+919876543210` | | **SIP Termination URI** | Your 60db SIP domain from **Dialer → Trunks** | | **SIP Username** | The 60db SIP username | | **SIP Password** | The 60db SIP password | 5. Click **Create / Save**. **What QCall does behind the scenes** (no action needed from you): * Creates an **outbound trunk** → sends outbound calls to your 60db SIP domain, authenticated with your username/password, using your 60db number as caller ID. * Creates an **inbound trunk** → matched to your 60db number. * Creates a **dispatch rule** → routes incoming calls on that number to your AI agent. **What QCall gives you back:** your **SIP URI** (shown in the dialer's SIP config / setup instructions, format `3.109.230.240:5060`). **Copy it — you need it for Part C.** > If you don't see the SIP URI in the UI, it's a fixed value for your QCall workspace — ask QCall > support and they'll provide it. *** # Part C — 60db: finish the inbound loop-back Inbound calls only reach your AI agent once 60db knows where to forward them. 1. Return to **60db Dashboard → Dialer → Trunks** → your **inbound trunk**. 2. Set the inbound **destination / forward URI** to your QCall **SIP URI** from Part B. * Enter it **without** the `sip:` prefix, e.g. `3.109.230.240:5060`. * If 60db asks for a full URI, use `sip:3.109.230.240:5060`. 3. Make sure the number from Step 4 is the one bound to this inbound trunk. 4. Save. Now the loop is closed: * **Outbound:** QCall → your 60db SIP domain → PSTN. * **Inbound:** Caller → your 60db number → 60db → `3.109.230.240:5060` (QCall) → AI agent. *** ## Testing **Outbound test** 1. In QCall, assign the new SIP dialer to a campaign or a Playground test call. 2. Call your own mobile. It should ring with your 60db number as caller ID, and the AI agent should speak when you answer. **Inbound test** 1. Assign an inbound assistant to this dialer/number in QCall. 2. From any phone, call your 60db number. It should connect to your AI agent. You can confirm both calls in 60db under **Dialer → Calls** (call history / recordings). *** ## Pricing (60db side) | Item | Cost | | - | - | | Number rental | ₹600 (\$6.00) / month, charged at purchase and each renewal | | Inbound calls | ₹0.30/min (\$0.003/min), billed per second | | Outbound calls | ₹0.30/min (\$0.003/min), billed per second | | Grace period | 48 hours after renewal; unpaid numbers are then released | QCall usage charges are billed separately by QCall. *** ## Troubleshooting | Symptom | Likely cause & fix | | - | - | | `Failed to create SIP configuration` on save | One of the SIP fields is wrong/empty. Re-check SIP domain, username, password. All are required. | | Outbound call fails / 401 / 403 at carrier | Wrong username/password, or credentials belong to a different workspace/trunk. | | 60db `409 DIALER_NOT_PROVISIONED` | Trunk not set up yet. Finish **Dialer → Trunks** (Step 3). | | 60db `403 DIALER_KYC_*` when buying a number | KYC not started, pending, or rejected. Complete **Dialer → KYC** (Step 2). | | 60db `402 RECHARGE_REQUIRED` | Wallet balance too low. Top up and retry. | | 60db `403 CALLER_ID_NOT_OWNED` | The phone number in QCall isn't rented by your 60db workspace. Use a number from **Dialer → Numbers**. | | 60db `502 CARRIER_LINE_DOWN` | Carrier is temporarily unavailable. Retry later or check line status in 60db. | | Outbound rejected (number/format) | Number must be E.164 with `+91` in QCall. | | Inbound call never reaches the agent | Part C not done, or wrong SIP URI. Verify the inbound trunk forwards to `3.109.230.240:5060`. | | "This phone number is already being used" | The number is already registered to another QCall dialer/workspace. Delete the old dialer or use another. | | Audio one-way or choppy | Codec mismatch. Ensure the trunk allows standard telephony codecs (μ-law/PCMU, 8 kHz). | *** ## Sources * [60db — Dialer](https://docs.60db.ai/features/dialer) * [60db — Buy Number](https://docs.60db.ai/api-reference/dialer/buy-number) * [60db — Set Caller ID](https://docs.60db.ai/api-reference/dialer/set-caller-id) * [60db — Line Status](https://docs.60db.ai/api-reference/dialer/line-status) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
