What Sipnetic is
Sipnetic is a free Android VoIP softphone that uses SIP accounts to connect with compatible VoIP providers, cloud PBXs, or enterprise telephony servers. It does not provide VoIP service, so calling requires an account from a SIP provider, and feature support can vary by provider. Calls can run over Wi-Fi or 3G/4G. The app supports multiple SIP accounts, QR-code setup, text and voice chat, SIMPLE presence, and system contact integration with a built-in contact editor. Telephony controls include multiple calls, hold, attended transfer, DTMF, number rewriting, and voicemail message waiting indication. Audio codecs include Opus, G.722, G.711, G.729, Speex, and GSM; video uses H.264 or VP8. Sipnetic lists TLS, SRTP, and ZRTP for calls and OTRv3 for chat. Google Play identifies video calling, ZRTP, and OTR as premium features and says paid features have not been purchasable there since December 26.
Good
- Supports multiple SIP accounts
- Works over Wi-Fi and 3G/4G
- Includes broad codec support
- Offers call and chat encryption
- No ads or user tracking
Watch out
- Requires an external SIP provider account
- Provider support for features may vary
- Some features are marked premium
- Paid features reportedly unavailable for purchase
Who it suits
It suits Android users who already have a SIP service account and need a softphone for compatible providers or PBXs. It also fits users wanting multiple accounts, messaging, and standard call controls.
Verdict
Sipnetic provides a broad SIP calling and messaging toolkit for Android, with codec, transfer, presence, and encryption options. Its dependence on an outside provider and uncertain premium purchasing are important considerations.
