MicroSIP vs SipPulse Softphone

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.

SipPulse Softphone is a professional softphone for telecom operators, virtual PBX providers, contact centers, ISPs and SCMs. It supports voice, video and messaging across Android, iOS, Linux, macOS, web and Windows. The browser version uses WebRTC and runs without installation. Voice calls can use Opus, G.722 or G.711 for HD audio; video supports H.264 and VP8, and instant messages use SIP MESSAGE. The technical specifications list TLS for signaling, SRTP for media and encrypted credentials. Accounts can be provisioned automatically over HTTP or HTTPS using XML configuration, including codec settings. Android ConnectionService links the app with system calls, and Janus Gateway is integrated with SipPulse SoftSwitch for WebRTC. The App SipPulse plan is free for iOS, Android, Windows and Linux, with unlimited users and installations. Mobile users need valid SIP credentials. White-label publication under a client's brand is offered, while the Chrome extension is marked as coming soon.
