SipPulse turns your iPhone into a professional SIP phone. Register with any standards-compliant SIP server and make high-quality voice calls over Wi-Fi, 4G, or 5G — without forwarding, number porting, or monthly per-seat contracts with a third party. Built on PJSIP — the same open-source stack used by millions of deployed SIP endpoints — SipPulse focuses on the three things a softphone has to do perfectly: register reliably, handle calls cleanly, and stay out of the way. CORE FEATURES • Full SIP calling — outbound and inbound voice, with native iOS CallKit integration so incoming calls look and feel like regular phone calls. • Push-notification wake-up — receive calls even when the app is closed or the device is locked. Compliant with RFC 8599 Push Notification Parameters for registrars that support it. • Messaging — send and receive SIP MESSAGE requests alongside your calls. Conversations are grouped by contact and persist across sessions. • Contacts — keep a local directory with favorites, search, and one-tap calling, video, or messaging per contact. • Call history — see every call with direction, duration, and timestamp. Filter by missed, incoming, or outgoing. • QR-code provisioning — scan a provisioning QR from your PBX or admin portal and your account is configured in one step. SECURITY AND QUALITY • TLS signaling and SRTP media for encrypted end-to-end calls (when supported by your server). • HD voice with wideband G.722 when the far end agrees; graceful fallback to PCMU/PCMA on constrained networks. • Automatic NAT handling and SIP keep-alives so registration stays healthy behind carrier NATs. STANDARDS SipPulse works with any SIP 2.0 registrar that speaks RFC 3261 — including OpenSIPS, FreeSWITCH, Asterisk, 3CX, and most hosted cloud PBX providers. UDP, TCP, and TLS transports are all supported. No proprietary lock-in. WHO IT'S FOR • Mobile workers who want their desk extension in their pocket. • IT teams standardizing on a single softphone across a fleet. • Service providers offering white-label softphone apps to customers. • Developers and VoIP professionals who need a reliable reference client on iOS. PRIVACY SipPulse does not collect analytics, does not embed advertising SDKs, and does not share your call metadata with third parties. Your account credentials stay on your device.
