In their own words
Siperb Mobile 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.
