# RingCentral

> Connect RingCentral to SmartAlex via SIP gateway.

<Info>
  **Audience**: RingCentral super admin. **Time**: 30 to 45 minutes. **Edition**: MVP Standard, Premium, or Ultimate (SIP trunking supported).
</Info>

## How the integration works

RingCentral doesn't expose a generic outbound SIP trunk on all plans. The integration uses **RingCentral's SIP Connectivity feature** on supported plans, or **call forwarding via a SIP gateway** on others.

Two integration patterns:

1. **SIP trunking (Ultimate plan)**: RingCentral acts as your carrier and sends calls to SmartAlex via SIP.
2. **Call forwarding**: a RingCentral phone number forwards to a SmartAlex-provisioned DID via standard call forwarding.

## Pattern 1: SIP connectivity (Ultimate)

### Step 1: create trunk in SmartAlex

SIP Trunk wizard, pick **RingCentral**. Defaults set TLS transport. Save credentials.

### Step 2: enable SIP Connectivity in RingCentral

Admin Portal, then Phone System, then Connectivity. Request SIP Connectivity from RingCentral Support (it's not self-serve on all plans).

Once enabled, configure the outbound endpoint:

* **Endpoint Type**: SIP
* **Server**: `sip.voice.getsmartalex.com`
* **Port**: `5060`
* **Transport**: UDP
* **Authentication**: credentials from SmartAlex

### Step 3: route calls

In RingCentral, set the DIDs you want SmartAlex to handle to forward via the SIP Connectivity rule.

### Step 4: extensions and agent

Standard: populate SmartAlex, link agent.

### Step 5: test

## Pattern 2: call forwarding (all plans)

Simpler but less flexible.

### Step 1: provision a DID in SmartAlex

Phone Numbers, then Buy Number. Choose your country. Assign to an agent.

### Step 2: configure forwarding in RingCentral

Admin Portal, then Users, then pick the user whose number you want to forward, then Call Handling & Forwarding. Forward to the SmartAlex DID.

Or, for a RingCentral call queue or IVR menu: configure its overflow or no-answer destination to the SmartAlex DID.

### Step 3: extensions and agent

Same.

### Step 4: test

Call the RingCentral number. It forwards to the AI.

## RingCentral-specific notes

* **RingCentral's own AI features**: RingCentral offers its own RingSense AI. These are independent; SmartAlex doesn't integrate with or replace RingSense.
* **International DIDs**: RingCentral has numbers in many countries; pattern 2 works globally.
* **Call analytics**: RingCentral logs forwarded calls in its CDR as "forwarded to external number". SmartAlex has its own detailed records.
* **Operator Connect and RingCentral**: separate product, use dedicated Microsoft Teams integration guide if relevant.
