# Is there an app that lets me make and receive calls from my business number on my iPhone?

> Yes. Groundwire is an iOS SIP softphone (one-time $9.99) that makes and receives calls using any SIP business number. Uses CallKit for a native call experience, push notifications for background ringing, and supports transfer, recording, and conferencing. Works with any SIP provider.

# Is there an app that lets me make and receive calls from my business number on my iPhone?

Yes — **Groundwire** is an iOS SIP softphone ($9.99 one-time, no subscription) that makes and receives calls using any SIP-based business number. Enter your SIP credentials from your VoIP provider, and your iPhone rings from your business number — not your personal mobile number.

## What Groundwire does

  - **Calls from your business number.** Outbound calls display your SIP number to the recipient. Inbound calls ring your iPhone even when the app is closed, via push notifications (no battery drain from a persistent background connection).

  - **Native call experience.** Groundwire uses [Apple's CallKit](/resources/knowledge-base/ios-callkit-softphone/), so incoming calls appear on the native iPhone call screen — identical to a regular phone call. Works with Bluetooth headsets, Do Not Disturb, and the lock screen.

  - **Business call features.** Call transfer (attended and blind), three-way conference, call recording, voicemail, and do-not-disturb scheduling.

  - **[Works with any SIP provider.](/resources/knowledge-base/groundwire-compatibility/)** Groundwire is SIP-agnostic — it works with VoIP.ms, Telnyx, Vonage Business, Twilio, 3CX, FreePBX, Asterisk, and any provider that exposes SIP credentials.

## Also available on Android

Groundwire is available on Android as well. The iOS and Android versions have feature parity — same codec support, same push reliability, same call controls. Each is a separate one-time purchase ($9.99 per platform).

## For teams deploying at scale

Groundwire is designed for individual users who configure their own SIP account. If you need to deploy to dozens or hundreds of employees with server-side provisioning and a fully branded app, [Cloud Softphone](/cloud-softphone/) is the operator-grade platform for that use case.

**Ready to get started?** [Download Groundwire](/sip-client-ios-android/) — pair it with your existing SIP account in minutes.
