Aria vs SipPulse Softphone

Aria is a native SIP softphone for connecting to standards-compliant SIP servers. It handles inbound and outbound calls, mute, hold, transfers, DTMF, presence, contacts, and call history. Audio support includes Opus up to 48 kHz, G.711, an adaptive jitter buffer, and local WAV recording. Desktop downloads are available for macOS, Windows, and Linux, with signed installers and in-app updates. The maker says iOS and Android apps are in testing and have no releases yet. A self-hosted push gateway is required for mobile apps to receive incoming calls in the background. Aria names Asterisk, FreeSWITCH, and 3CX as compatible server examples and also works with the maker's AriaRoute hosted PBX. The privacy policy says it has no telemetry or analytics and stores credentials, contacts, call history, and recordings locally. SIP signalling can use TLS and media SRTP, but the maker says this is not end-to-end encryption. Aria is free for personal and non-commercial use; business use requires a separate commercial licence.

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.
