SessionTalk Softphone vs Siperb Mobile Softphone

SessionTalk Softphone provides native softphone apps alongside SessionPBX, which combines voice and video calling, team messaging, and hosted PBX service. Apps are listed for Android, iOS, macOS, web, and Windows. The softphones can connect to SIP-based PBX and hosted platforms, including Asterisk, FreePBX, FusionPBX, 3CX, FreeSWITCH, Kamailio, OpenSIPS, BroadSoft, Metaswitch, PortaOne, VitalPBX, and Yeastar. Calling supports up to six concurrent calls, transfer, recording, and HD video using H.264, VP8, or VP9. Depending on plan and setup, messaging may include direct and group messages, file sharing, and SMS through a SIP provider. Teams Phone and Teams Business include hosted phone service, but customers provide their own SIP carrier for external calls and pay that carrier directly. Setup can use a mobile QR code or a one-time desktop link. A 14-day trial includes full feature access and requires no credit card. Monthly plans include Teams Phone at $20 a month, Teams Business at $40 a month, Generic at $100 a month, and white-label mobile or desktop at $400 a month each.

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.
