Do I need a VoIP number to use Groundwire?
Yes. You need a SIP/VoIP account to use Groundwire. Groundwire is a SIP softphone app that connects to the SIP server your VoIP provider gives you. The provider gives you the number, the server, and the credentials; Groundwire handles everything on your phone.
How do I provision a mobile softphone app for hundreds of users?
Provisioning a mobile softphone for hundreds or thousands of users relies on automated server-side provisioning, where your backend pushes each user's configuration to the app so no one types SIP settings by hand. QR codes, MDM enrollment, and bulk import through an admin portal cover smaller or device-specific deployments; manual per-user setup is the only method here that does not scale.
How do I publish a VoIP app to the App Store and Google Play?
Publishing a VoIP app means submitting to both the Apple App Store and Google Play, each with VoIP-specific rules that generic app guides skip, mainly around push notifications and background modes. On iOS you need an Apple Developer account, CallKit integration so incoming calls appear on the native call screen, and PushKit VoIP pushes that report every call to CallKit. On Android you need a Google Play Console account, Firebase Cloud Messaging for reliable push, and a foreground service notification if the app stays connected for call readiness. Apple review typically runs 3–7 business days and Google 1–3. If you use a white-label platform, the vendor handles the technical build and submission while you supply branding and configuration.
