In their own words
Aria
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.
Linphone
Linphone combines VoIP voice and video calling, instant messaging, and videoconferencing in one application. It uses SIP and SIP SIMPLE to interoperate with IP-PBXs, proxies, SBCs, and other SIP systems. Calling features include HD audio and video, call forwarding, concurrent calls, recording, DTMF, and Bluetooth headset support. Its Flexisip or SaaS conferencing option supports meetings with up to 50 participants and screen sharing. Messaging features depend on setup: Flexisip supports group chats, file sharing, read receipts, reactions, voice messages, and ephemeral messages; SIP SIMPLE provides basic one-to-one messaging with third-party accounts. Security features include SIP/TLS, SRTP, SRTP-DTLS, ZRTP, end-to-end encryption for exchanged media, and post-quantum encryption using CRYSTALS-Kyber. Flexisip can be hosted on premises and connected to an existing SIP server for group messaging and videoconferencing. Linphone is open source under GNU GPLv3, with proprietary licensing available for closed-source modifications. The app is available on Android, iOS, Linux, macOS, Windows, and web, with API and self-hosted options. Its free SIP service is for individual users and has no guaranteed support; paid support and maintenance are available by contacting the company.
