Siperb Mobile Softphone vs SipPulse Softphone

Siperb Mobile Softphone puts an office phone extension on an iOS or Android device and connects it to an existing PBX or SIP system. It supports audio and video calls, attended and blind transfers, three-way conferencing, DTMF, call history, CDR, and buddy presence. Its listed end-to-end encryption uses TLS and DTLS-SRTP. When the app is backgrounded, locked, or restarted, Siperb’s proxy uses Apple APNs or Google FCM to wake it and deliver calls. Mobile devices must use Proxy Registration Mode, which is also required for push notifications. The same account works across web, Windows, macOS, Linux, iOS, and Android, sharing contacts, settings, and call history. Supported PBXs include Asterisk, FreePBX, FreeSWITCH, and SIP systems that can provision an extension. Personal is free; Business costs £2.00 per month per domain user, and Business Pro costs £5.00 per month per domain user.

SipPulse Softphone is a professional softphone for telecom operators, virtual PBX providers, contact centers, ISPs and SCMs. It supports voice, video and messaging across Android, iOS, Linux, macOS, web and Windows. The browser version uses WebRTC and runs without installation. Voice calls can use Opus, G.722 or G.711 for HD audio; video supports H.264 and VP8, and instant messages use SIP MESSAGE. The technical specifications list TLS for signaling, SRTP for media and encrypted credentials. Accounts can be provisioned automatically over HTTP or HTTPS using XML configuration, including codec settings. Android ConnectionService links the app with system calls, and Janus Gateway is integrated with SipPulse SoftSwitch for WebRTC. The App SipPulse plan is free for iOS, Android, Windows and Linux, with unlimited users and installations. Mobile users need valid SIP credentials. White-label publication under a client's brand is offered, while the Chrome extension is marked as coming soon.
