What Sipnetic is
Sipnetic is an Android SIP softphone for connecting to a VoIP provider, cloud PBX, or enterprise telephony server. It supplies the calling interface, not VoIP service, so you need an account with a SIP service provider; support for individual features can vary by provider. Calls can use Wi-Fi or 3G/4G, and the app supports multiple SIP accounts, QR-code account setup, text and voice chat, and SIMPLE-based presence. Call controls include holding or transferring calls, DTMF, number rewriting, handling multiple calls, and voicemail message waiting indication. Audio codecs include Opus, G.722, G.711, G.729, Speex, and GSM; video calls use H.264 or VP8. The maker lists TLS, SRTP, and ZRTP for calls, and OTRv3 for chat encryption. Google Play identifies video calling, ZRTP, and OTR support as premium features and says paid features have not been purchasable there since December 26. Sipnetic works with system contacts and includes a contact editor. Its maker says the app has no ads, tracking, or personal data collection; crash reports may include non-personal device details such as make and model. The September 25, 2026 changelog notes improved Android 16+ support and DNS over TLS in version 1.1.11.
