About

Kamailio® (successor of former OpenSER and SER) is an open-source SIP server released under GPLv2+, able to handle thousands of call setups per second. Kamailio can be used to build large platforms for VoIP and real-time communications, presence, WebRTC, Instant messaging, and other applications.

Among the powerful features, are asynchronous TCP, UDP and SCTP, secure communication via TLS for VoIP (voice, video, text); WebSocket support for WebRTC; IPv4 and IPv6; simple instant messaging and presence with embedded XCAP server and MSRP relay; asynchronous operations; IMS extensions for VoLTE; ENUM; DID and least cost routing; load balancing; routing fail-over; accounting, authentication and authorization; support for many backend systems such as MySQL, Postgres, Oracle, Radius, LDAP, Redis, Cassandra, MongoDB, Memcached.

About

Stop eavesdropping on your calls, encrypt your VoIP calls! Don't like it when people eavesdrop on your conversations? Neither do we, that's why we offer free encryption for all your text, voice and video communications with TLS/SRTP and ZRTP. Our VoIP softphone will look everywhere for your contacts and will display them in a combined list for easy access. Outlook, windows/mac, LDAP, XMPP, XCAP, Android, iOS. You name it, we got it and we will lookup incoming calls as well so you know who calls before you answer. Zoiper runs on a multitude of different platforms. No matter if you are using macOS, Linux or Windows. iOS, Android or a browser, we’ve got a solution for all (and we are working hard on addition even more). Ignore the buzzword above, it just means we do Audio, Video, Fax, Presence and Instant Messaging. All from one intuitive interface.
