Make voice and video calls, send messages, and stay connected with Acrobits Softphone App, a powerful and feature-rich SIP softphone designed for all your calling needs. BEFORE YOU BUY Acrobits Softphone is a SIP client app. It does not come with phone service: you sign in with the SIP account your VoIP provider, PBX or employer gives you. Note: this app does not support call transfer or conference calling. Acrobits Softphone works out of the box with many of the most popular VoIP providers and Bluetooth devices on the market. If you already have SIP service, from work or from any VoIP company, you are ready to go. It brings all the popular features you expect from a SIP app, including support for 5G, voice and video calling, push notifications, call handover between WiFi and data, multi-device compatibility, lifetime access to support and updates, and more. Keep a work line separate from your personal number. Carry a home-office extension in your pocket, or call over WiFi while traveling. Calls run over WiFi and mobile data, so your sip phone works wherever you have a connection, at home or abroad. Bring the account you already have. Acrobits Softphone is a standards-based SIP client, so it registers with Asterisk, FreePBX, 3CX, hosted PBX platforms and everyday business VoIP services alike. Sign in with your SIP account and you have a business softphone dialer that carries your work line anywhere. Encrypted SIP calling keeps every conversation private. Calls stay clear with support for popular audio standards, including Opus, G.722, G.729, G.711, iLBC, and GSM. Need video? It goes up to 720p HD with both H.264 and VP8. Pair it with the Bluetooth headsets and car kits you already use. Push notifications do the waiting, so the app stays reachable in the background. And voice is not the whole story: send messages from the same app when a call is too much. You can set it up your way, with custom call settings, ringtones, and UI options. And because it follows open standards, you are never locked in. Switch providers whenever you like and keep the same app, the same contacts, and the same settings. Acrobits Softphone makes it easy to communicate with friends and family on any device. And it runs on virtually all iPhones and iPads. Don't worry about hidden fees or subscriptions. You pay once, and lifetime support and updates are included. Secure VoIP is part of the deal rather than an upgrade. Try it today, and see why softphone users have trusted Acrobits since 2009.
