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.
SessionTalk Softphone
SessionTalk Softphone provides native softphone apps alongside SessionPBX, which combines voice and video calling, team messaging, and hosted PBX service. Apps are listed for Android, iOS, macOS, web, and Windows. The softphones can connect to SIP-based PBX and hosted platforms, including Asterisk, FreePBX, FusionPBX, 3CX, FreeSWITCH, Kamailio, OpenSIPS, BroadSoft, Metaswitch, PortaOne, VitalPBX, and Yeastar. Calling supports up to six concurrent calls, transfer, recording, and HD video using H.264, VP8, or VP9. Depending on plan and setup, messaging may include direct and group messages, file sharing, and SMS through a SIP provider. Teams Phone and Teams Business include hosted phone service, but customers provide their own SIP carrier for external calls and pay that carrier directly. Setup can use a mobile QR code or a one-time desktop link. A 14-day trial includes full feature access and requires no credit card. Monthly plans include Teams Phone at $20 a month, Teams Business at $40 a month, Generic at $100 a month, and white-label mobile or desktop at $400 a month each.
