What Sipdroid is

Sipdroid is a free SIP/VoIP client for Android that can route calls from the phone’s built-in contacts app over VoIP. Its integration with Android’s built-in dialer lets the standard calling interface initiate calls or ring. In the app’s settings, you can select VoIP or standard phone calls according to Wi-Fi login status, number prefixes, or both. Sipdroid supports SIP and call recording. The project’s news says version 3.0 added TLS encryption, and release 6.5 lists Android 14 compatibility. Google Play’s developer-provided data safety disclosure says the app may collect personal information, shares no data with third parties, and encrypts data in transit. The Google Play listing recommends reserving a free VoIP PBX through pbxes.org for optimal battery usage; SIP trunks can be managed in a web browser. Sipdroid is distributed under the GNU General Public License version 3 or later. Its developer is i-p-tel GmbH, identified in Mainz, Germany, and the listed support email is [email protected].
