What it is
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.
