MicroSIP is a free Windows desktop softphone for business communication and professional VoIP use. It makes voice and video calls through SIP providers or PBX systems, and can also call an IP address or domain name directly. Call Manager handles multiple simultaneous calls, conferences, blind and attended transfers, and instant messaging. Listed video codecs include H.264, H.263+, VP8, and VP9; DTMF options include in-band, RFC2833, and SIP INFO. SIP signaling can use TLS, while media protection options include SRTP and DTLS-SRTP. MicroSIP says it does not provide user accounts, phone numbers, or telephony services and has no access to end-user information. Windows is listed as supported; Linux, macOS, and BSD are listed for use via Wine. Android, iPhone, and iPad are not supported. The standard edition lists video support, while Lite does not. The project uses the GNU GPL v2 license. A custom-branded softphone build costs €150, paid once; future updates, modifications, or additional features are billed separately.
