PortSIP Softphone
PortSIP Softphone is a free app for Windows, iOS, and Android with browser calling and SIP support. It is the legacy app for PortSIP PBX v16.x; the maker directs users of PBX v22.x to PortSIP ONE. The broader PortSIP PBX offering brings calls, messaging, and meetings together, including call routing, SMS, WhatsApp, team messaging, contact center tools, and voice and video meetings. Contact center functions include skill-based routing, queue strategies, live wallboards, analytics, real-time monitoring, and training tools. The maker also describes AI features for call and voicemail transcription, notes, summaries, and sentiment analysis. PBX deployments can run on customer infrastructure, Azure, AWS, or GCE, in a cloud, data center, or on premises using Docker. Microsoft 365 integration supports user provisioning, single sign-on in web and native apps, and directory and contact syncing. The PBX Free Edition costs nothing and supports 3 extensions and 2 simultaneous calls. Paid PBX licenses require a quote and may be perpetual or annual.
