In their own words
MicroSIP
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.
Sip:phone
Sip:phone extends Sipwise Class 5 Softswitch and CPBX services to Android and iOS as a mobile extension of an existing business phone system. It is intended as a white-label client for operators using Sipwise NGCP, who can customize its appearance and publish it under their own name in the Apple and Google app stores. Subscribers are managed on Sipwise C5 through interfaces such as its web interface or REST API; users can sign in with a username and password or scan a server-generated QR code. Calling includes audio and video, hold, two simultaneous calls, three-way conferences and blind or attended transfers. The app synchronizes phone contacts with Sipwise C5 subscribers and can show presence for favorite contacts. Administrators can configure whether a desk phone or mobile app rings first, or have either ring alone. Sip:phone requires an existing Sipwise server account and is not intended to support emergency calls. The App Store download is free, but commercial use requires a Sip:Phone App license; pricing is available from Sipwise Sales.
