PortSIP Softphone vs SessionTalk 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.

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.
