# RingCentral

> Connect Simple AI to RingCentral Contact Center and RingEX via SIP

Simple AI connects to RingCentral over a SIP trunk. RingCentral keeps routing, queues, and agent state; Simple AI handles the conversations routed to it and hands them back for live agent escalation.

Both RingCentral Contact Center and RingEX (for straightforward call routing) work over the same trunk.

## What You Can Do

* **Inbound routing** — RingCentral answers the call, runs IVR and queue routing, then transfers it to Simple AI's SIP endpoint.
* **Outbound campaigns** — the RingCentral dialer handles pacing and compliance, and transfers connected calls to Simple AI.
* **Direct outbound** — Simple AI places calls through the trunk with your existing caller ID.
* **Live agent escalation** — Simple AI transfers back to a RingCentral queue, extension, or external number.
* **Context on transfer** — call metadata rides along in `X-` prefixed SIP headers for screen pop and CRM lookup.

## How It Connects

```
Customer → Carrier → RingCentral (IVR / queue) → Simple AI
                            ← escalation back ←
```

1. RingCentral receives the call and runs your IVR and routing rules.
2. A transfer sends the call to Simple AI over the SIP trunk.
3. Simple AI runs the conversation and transfers back when escalation is needed.
4. RingCentral queues the returned call and delivers it to an agent with the transferred context.

## Setup

1. Set up SIP connectivity — RingCentral Cloud Connect or SIP peering — pointing at Simple AI's SIP endpoint, and allowlist our signaling and media IPs.
2. Give your account team the RingCentral endpoint, auth details, and the numbers involved in E.164 format.
3. Point the IVR nodes or queue overflow rules that should use the AI at the transfer destination, and set a return destination for escalation.
4. Test inbound, outbound, and escalation, verifying caller ID, audio, DTMF, and agent-side context.

Your account team configures the Simple AI side. Contact [support@usesimple.ai](mailto:support@usesimple.ai) to get started.
