What Telephone is

Telephone is a SIP softphone for making and receiving VoIP calls on a Mac over the Internet or a company network. Calling requires a SIP account from a phone provider or a compatible router. The free version supports up to three simultaneous calls and displays the last three calls in its history; Telephone Pro raises the simultaneous-call limit to 30 and reveals up to the last thousand calls. Telephone can answer or decline calls from notifications, find names in macOS Contacts, and become the default handler for calls initiated there. It also opens sip: and tel: links and can call a number selected in another app through macOS Services. Supported codecs include Opus, G.722, G.711 A-law, and G.711 μ-law, and the maker says most SIP providers should work. With TLS selected as SIP transport, voice uses mandatory SRTP; UDP and TCP connections to the configured server are in cleartext. The maker says application data is stored locally and its apps collect no user data or usage analytics. Telephone 1.6 added Apple Silicon support and the modern macOS look. The product is made by 64 Characters UG, based in Berlin, Germany.
