# How do I set up Groundwire with RingCentral?

> Groundwire cannot register directly with RingCentral. There is no setup procedure to follow: Groundwire (or any third-party SIP client) cannot register against RingCentral's service. RingCentral runs a closed ecosystem and does not publish the SIP server, port, or credential information third-party softphones need.

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

## Why RingCentral does not support third-party SIP softphones

RingCentral has removed all public documentation for third-party SIP device registration. It uses SIP internally but does not publish the SIP details third-party softphones need, so customers stay on its native app for the supported experience.

## What this means for Groundwire users

  - Groundwire cannot register with RingCentral credentials.

  - For direct use with RingCentral, the supported option is RingCentral's own native app.

  - Some third-party guides claiming to set up RingCentral with Groundwire (or Bria, Zoiper, Linphone) are outdated, because the public documentation for this setup is no longer available.

## Which SIP providers work with Groundwire

Groundwire works with [open SIP providers](/resources/knowledge-base/groundwire-compatibility/). Examples include:

  - **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

## RingCentral BYOC setups with Groundwire

Groundwire can work in a RingCentral setup only when you control the SIP trunk. In some enterprise bring-your-own-carrier (BYOC) arrangements, calls may be bridged through a SIP trunk on your side rather than RingCentral's, and Groundwire can register against that trunk. This is uncommon and may be limited to certain enterprise plans. Talk to your RingCentral account manager.
