# How do I set up Groundwire with RingCentral?

> Groundwire does not work with RingCentral. RingCentral runs a closed ecosystem and does not publish SIP credentials for third-party softphones. If you want to use Groundwire, switch to an open SIP provider like VoIP.ms, Twilio, Vonage, or Telnyx.

**[Groundwire](/sip-client-ios-android/) does not work with RingCentral.** RingCentral runs a closed ecosystem and does not publish SIP server, port, or credential information for third-party softphones. There is no setup procedure available — Groundwire (or any third-party SIP client) cannot register against RingCentral's service.

## Why RingCentral blocks third-party SIP softphones

RingCentral has removed all public documentation for third-party SIP device registration. This is a deliberate product decision: RingCentral wants every customer using its native app, not an alternative softphone, so it can control the user experience, billing, and feature roadmap end-to-end. The technical infrastructure exists (RingCentral runs SIP internally), but it is not exposed to customers.

## What this means in practice

  - You cannot enter RingCentral credentials into Groundwire.

  - "Best softphone for RingCentral" has only one answer: RingCentral's own native app.

  - Any third-party guide claiming to set up RingCentral with Groundwire (or Bria, Zoiper, Linphone) is outdated — the documentation that made it possible has been removed.

## If you want Groundwire, switch providers

Groundwire works with [any open SIP provider](/resources/knowledge-base/groundwire-compatibility/). The most common choices are:

  - **VoIP.ms** — see [setup guide](/resources/knowledge-base/how-do-i-set-up-groundwire-with-voip-ms/)

  - **Twilio** — [Elastic SIP Trunking with TLS + SRTP](/resources/knowledge-base/how-do-i-set-up-groundwire-with-twilio/)

  - **Vonage Business / SIP Trunking** — [VBC and SIP Trunking plans only](/resources/knowledge-base/how-do-i-set-up-groundwire-with-vonage/)

  - **Telnyx, Bandwidth, PhonePower** — see provider documentation

## Edge case — RingCentral with a Bring-Your-Own-Carrier setup

RingCentral does support some BYOC arrangements at the enterprise tier, where calls are bridged in via a SIP trunk you control. In that scenario the SIP trunk is on your side, not RingCentral's, and Groundwire can register against the trunk. This is uncommon and only available on specific enterprise plans — talk to your RingCentral account manager.
